OK, well before someone gang-piles on me like most of the other posters on here who hate the GMA950 in the mini, I will qualify my statements by saying:
1) I have a Macbook with the intel GMA950 (1.83C2D, 2G ram) and while it works fine for my basic laptop needs, it is sadly lacking when compared to all but the most basic PC desktop towers being sold by Dell or HP, etc.
The Mini is the SAME THING as a Macbook but packaged differently, so I can speak with some authority on its performance. for the prices being asked, apple could EASILY include even a 1600 series radeon and still turn a fair profit - as well as boost sales considerably to switchers who already own a good quality LCD monitor.
2) I would NEVER buy anything with an integrated monitor unless it is a laptop where you need one for portability. Applecare is fine, but I expect and have always gotten 5 years from a good machine, not three. On day 1 of the 4th year of ownership if the monitor dies you are SOL and you have to scrap the whole system. Not acceptable to me, so I'll never buy an iMac.
3) There is NO REASON that a mac owner should not want to play a few UB games like CivIV Warlords (won't run on the GMA chipset) or Imperial Glory for mac or whatever. Saying wanting to play non-console games and being a mac guy are mutually exclusive is ignorant IMHO and shame on anyone who responded that such a person should buy a Dell. OSX is perfectly capable - it's the hardware that is lacking for anyone who can't/won't buy a 24" iMac or MacPro (read $$$$$).
If Steve & Co. at Apple ever release a mid-tower or Mini with dedicated graphics I will buy it and gladly pitch my last remaining PC out the window but until that time, half my money has to grudgingly continue to support the M$ corporate machine
