I personally like the slickness of Mac - especially iMac. Their real time video effects in Photo Booth, the remote control

, the machine itself - is so good. They must have put in soo much work - it shows. It looks like a table-top-ipod. If you are a home user or a creative proffessional (photographer/movie maker/etc) - mac rocks.
Vista - many ideas taken from Mac OSX - there is a lot of originality too. They are doing a lot with file-metadata. Looks good initially. Did not get to try it for too long.
While we are at it, you might want to check this out:
PhillRyu.com - Reliving the Keynote
there were these captions at WWDC:
"Mac OSX Leapord: Introducting Vista 2.0"
"Redmond has a cat, too. A Copycat."
For the un-informed, Mac OSes are cats - cheetah, leapord, tiger, jagaur, etc.
Btw, Did anyone try developing something on mac? Code warrior looked ancient at best in comparison to Visual Studio. XCode - is slightly better than Codewarrior but many releases away from coming close to VS. Developing anything on mac is a night mare - it is not just the unfriendly IDEs - there are other problems. Perhaps this is why no eco system evolved arnd mac and may be this is why despite die-hard loyals, Mac will just have 5% of the market share.
M$ might be using Apple's UI research centers as their personal UI labs, they might be un-ethical and copy ideas, still coding on win is an experience much better than on Mac.

PS: can I do something so that the "cat"s in my post dont get interpreted as CAT - Common Addmission Test?
