Memory leaks in Leopard and some of the hardware they put in their computers, namely the ATI 2600 HD video card, I really wish they would have chosen a better video card for the iMacs because its the only downfall of the computer. As posted earlier, I have noticed problems with eBay/Safari, it doesn't seem to load pages well...and yes it is a problem with this combination because it works fine on my PC using eBay/IE. Another thing, for those die hard Mac fans, this thread isn't something to take offense to because its just pointing out areas of improvement. If there wasn't room for improvement then there wouldn't be updates. I like OS X and I think Apple is one of the more honest corporations out there (if thats possible), but every company has flaws in there product. Cheer up, at least its not 2012 yet.
None of this has anything to do with the Mac OS. The thread title suggest annoyances with the way Apple designed the OS. You are talking about stuff that's not the inevitable. Safari will improve as time goes by. Remember Internet Explorer has been around since Windows 95 or maybe earlier and it still sorta sux but software developers use I.E to build their websites which is retarded, they should use Firefox which will make the website more compatible with other browsers such as Safari, so it's not Apple's fault that Safari has annoyances with Ebay.
Think about it, there are now millions of websites on the internet, is Apple suppose to know how to program Safari to work with all of them? No, it's up to the web developer to stop using I.E with those dumb active X controls.
Lastly, you obviously are a bit ignorant about the Mobility Radeon HD2600XT. It's a very fine GPU, it's NOT the 2600 Pro which does suck.
I play Bioshock on my new iMac with very decent frame rates and C&C. You should actually "use" something before just posting wrong info.
