Mac only games that are good would be so cool.
Semisonic: do you know anything about Macs at all? First, while the Video cards in the laptops and i/e/mini Macs might be getting a bit long in the tooth, the PowerMacs are able to use the most modern cards on the market right now.
Also, while there are thousands of various programmes you can buy and run on Windows, the big programmes that anyone would ever need are generally ported to the Mac or have equivalents. Also, due to the fact that OS X is Unix based, there is a whole slew of Open Source software out there that you can use.
Bob: Virtual PC is not slow because of Microsoft, it's slow because it has to translate processor instructions between two different types of processor, not to mention the hardware emulation thrown on top as well. Virtual PC is slow on Windows as well because it still emulates a whole computer and doesn't access hardware directly.
To the person who brought up Doom 3...it's not because it was badly ported, it's because OS X handles Open GL very differently than a Windows computer and because of the differences between RISC and CISC processors. When Quake 3 was first released for OS X it had the same performance problem, but over time Apple, the porting house, and the video card makers made their own enhancements and tweaks and now Quake 3 runs just as fast on a Mac as a PC.
