Maybe theoretically you should do that, but I don't know anyone that actually does on Windows or OS X. In both cases you aren't actually running with your full powers all the time, and get prompted to escalate if something needs admin access.
The default account created in Mac OS X has password authentication. Your password is the unique identifier. Most people use the default account created by the OS for day to day computing.
Commercial software shouldn't be installing malware...I mean tons of it now has all kinds of DRM that is arguably malware, but...
While I'd rather run something without giving it full access to the system, ultimately you're trusting the publisher either way.
When the software is running with superuser privilege and connects to servers that can be controlled by anybody such as in many online games for Windows, the content downloaded from the server can be written anywhere in your system. This allows keyloggers, backdoors, and malware rootkits to be installed.

I really doubt they double count things like that, given they're counted separately. I suppose there might be some validity to it if they did.
They count the number of items in each vendors security releases. Mac OS X includes Flash, Java, & etc by default so vulnerabilities in those are counted for Mac OS X because included in Apple security releases. Often these items constitute the majority of vulnerabilities in the security release. It is only valid if Windows users don't install Flash, Java, various ActiveX components, codecs, etc, etc, etc...
I'm not seeing why you're saying there's any difference. I don't use IE or Safari as my primary browser, though there may be some validity to including one or the other in the list of OS issues, but at any rate neither yet sandboxes plug-ins to my knowledge.
There's a flag that can be set for that, but I'm not sure where you're getting it from that article. Regardless 'some' is better than 'none'.
Except for Chrome which is sandboxed, all browser are susceptible to the security problems of the underlying OS but these issues arise in more than just the browser. An example of how they are different is Java has no security mitigations (DER or ASLR) in Windows (as shown in article) but Java has hardware based DEP and partial ASLR in Mac OS X as Java is 64 bit in OS X. Also, Mac OS X randomizes memory space into 4 byte chunks making it more difficult to defeat ASLR while Windows uses 64 byte chunks. Like you said, some is better than none.
Security mitigations, such as DEP and ASLR, can be optionally set in Windows OSes for various reasons such as support for legacy software. A lot of software for Windows comes with weak security by default and will break if the user tries to modify its settings. In Mac OS X, apps have a standard level of security mitigations dependent on the type of process (32 or 64 bit) that are set at that standard level when the app is compiled and not modifiable as in Windows (Opt-in, Opt-out, etc).
Which is different from Windows how?
Because Windows has a history of malware that achieves privilege escalation and Mac OS X does not? Check out these from late November 2010:

I imagine Santa Rosa would be long gone by summer '08.
Why? Is Santa Rosa not due out around spring / summer 2007? I am sure it will still be around a year after it is released.

This device is precisely why I haven't replaced my Airport Express (see sig). I sure hope this turns out to be true because this is exactly what I've been waiting for!
New nano and 23" iMac would be sweet too, although I don't need a new computer so it doesn't really affect me much.

I thought 10 Mega Pixels were possible with some tech that is suppose to arrive at the end of this year for phones.
The weak link is the lens. Basic physics says that the resolving power of a lens is proportional to it's diameter divided by the wavelenght of light. Light is not going to change any time soon so if you want to get a clear sharp image you need a certain physical diametr lens. If for some reason you can't have a big lens then what's the point of using a 10MP sensor? Actually if the device is size constrained using fewer pixels on the same size sensor (larger pixels) will improve low light performance. Bottom line: There is an optimum number of pixels, more is not better.
On the other hand if you are selling to un-educated buyers "we got more MPs" is good for marketing purposes even if it is counter productive on technical grounds

Why doesn't Intel just not support USB 3 and allow Thunderbolt to be used on other manufacturers chipsets? I mean I'm all for competition, but if one port is obviously superior but could potentially fail due to lack of adoption..

Well, I just sold my iMac, so I'm coming to you all from the tiny screen of my Nokia N70.
I'm looking to aquire a MacBook. Here in the UK we have our iPod rebate deal until mid-October, which will effectively knock the price of a Nano on eBay off the price of my machine.
What would you say, will there be MacBooks before mid-October? I don't want to wait any longer than that. Should I bother waiting or buy now?

I'm thinkin' Apple should have gone with "iApp Store" (u heard it here FIRST! Let me get a trademark/patent on that) b/c Microsoft is just a big ole' COPYCAT...lol :D
It's not easy to pronounce "iApp Store". It wouldn't have worked out too well.
Apple should have patented "AppStore" as one word instead of two words "App Store". Or should have patented both to be safe.
Anyways, phonetically both sound the same, and that may be a good argument; it worked for Microsoft when they sued "Lindows".

I had an app rejected because the icon was a cartoon of the presidential seal where the eagle, in one claw, was holding an iphone-looking phone, which I drew myself, and which was probably 12 pixels x 6 pixels or so in size (in an overall icon that was 57px x 57px.)
But apparently including a 3/4 scale photo of an iphone is fine.
Whatever.

I just want them to bump up the Macbook so then I can go ahead and buy my fist Mac. I just want to buy it when its the most current.
Ya, that's that I'm hoping. For the same reason too. I've used macs forever, but never owned my very own (other than an old PowerMac 7500). I also hope they update the ipod soon, I want to get the latest and greatest but I need to order by wednesday :-p

Oh man. Verizon early termination fee, here I come.
Yeah, this is pretty exciting news. I had already planned to call Verizon this morning to see when my contract is up.
EDIT: $175 termination fee per phone and a good while to go on the contract. Yeouch! I may just have to keep my fingers crossed that Verizon Wireless gets the iPhone late next year.

Is anyone here educated enough to explain to me how to compile and run this thing?
I can't find a way to install avahi. Tried installing it via fink - no luck.
MacPorts requires xcode, but I don't really want to install xcode. takes up a lot of space.
Even though I know some things I'd still prefer if someone would make a step-by-step how-to for me.
Thank you in advance.

Umm, you do realize the processor can be 10000000x faster, the system is still completely hammed by the 5600rpm hard drive they put in there. Most tasks are faster on an Air then a 17" Pro. And if you're doing heavy lifting get a Mac Pro. People who bought the new processors don't enjoy the benefits 90% of the time.
You must be a spec sheet reader, not someone who intelligently analyzes what they buy.
...and you think most people who buy a MBP won't swap out the drive for a 7200RPM drive or an SSD and max out their memory?
Intelligent...no genius level thinking!

If you need it get it now. If you can wait 6 months then wait. What is out is better than what you have, just be ready than in 6 months there will be something better. This is always the case even if you stay in the Win Camp.

Apple is a terrible company when it comes to ETHICS and people need to just understand that basic fact of life when dealing with them. They are greedy greedy greedy and they don't CARE what you think about them, what you want in a product and whether you wasted months working on an application that they just reject for the most ridiculous illogical reasons ever. This goes to show why NO COMPANY should be allowed to DICTATE (as in a dictatorship) terms for software releases on ANY platform (No, I don't care that it's based on a "phone" platform; it's STILL a computer; the iPod Touch is STILL a computer). We need a freedom of information/software/market act for software releases on all platforms. Apple has a monopoly on software distribution for the iPhone/iPod Touch computer platform and that simply should not be allowed. If you create a new hardware platform that is open to software development, that market should be independent of the company pushing the platform since clearly that constitutes a monopoly of software for that platform and leads to BS nonsense like this example shows. Imagine if they wanted 30% of all profits for the Mac platform and insisted software for the Mac could only be sold through iTunes.... That would never stand the light of day. Yet apparently it's OK if OSX is put onto a hand-held mobile computer and then forced to interface through iTunes (shakes head). As usual, the real loser here is the consumer who does not get all the software for the platform that he/she should be able to get. Instead you get mountains of two-bit 99 cent throw-away applications because no company in their right mind would put a lot of money into developing a really good application only to have Apple reject it on a whim!
Yes I know that you brain-washed types that worship Steve Jobs will scream and moan about this sort of comment since you seem to think that Steve should be allowed to do ANYTHING he wants in this world and have some contorted view of Capitalism that seems to think competition doesn't include Apple since they are somehow special and magical and should be left alone to do things like extort 30% off the top of all 3rd party software (very Mafia-esque IMO), but I say I don't care what a bunch of brain-washed groupies think so do me a favor and spare me your opinions. I couldn't care less about any form of fan-boy or fanatical viewpoint on ANYTHING Apple related since it will clearly be completely 100% Apple biased and therefore 100% WORTHLESS. Yes I already know you think it's Apple's hardware and therefore they have no market responsibilities to ANYONE. I think that's a load of horse manure. They exist in a country based on competition and if they don't like it, they should move to Communist China where there is none.

What if she had decided to not swerve off the road and instead run into the back of your car. When the insurance companies and police look at it, she'd be in the right (and be covered) and you'd be in the wrong with a screwed over car.

...I would like to be able to purchase a machine without an integrated display (aka iMac). This machine would have a graphics card in a standard slot so that it can upgraded. It would be great also to be able to remove and upgrade the hard disk, space for a second hard disk is would be a nice to have.
Currently I'm stuck in the middle between an iMac (I want a separate display, and some upgrade paths) and Mac Pro (too upgradeable for my needs, and way too expensive).
Apple really needs a pro-sumer box.

I'm not so sure that 4GHz is a given. Doesn't that pesky speed of light put a practical cap on clock frequency? At 4GHz a signal doesn't have time to cross the chip in one clock, so is there any point to such high frequencies?
You can already overclock 3.6GHz and 3.8GHz Pentiums to 4.0 GHz.
Remember that the pulse width is the reciprocal of frequency. At 4 GHz, the pulse width is 250 picoseconds. Light travels 0.000075 km in 250 picoseconds. There are 1 million mm in a km, hence light travels about 75mm in that time.
The size of the Core 2 chip is 143 square mm, or about 12mm x 12mm and getting smaller with each new process generation. At 4GHz, a single pulse can go back and forth across the chip at least 6 times.
In practice, propagation delays of this type are analyzed by CAD tools and the chip's physical layout is designed to minimize the signal path.
