What's the big deal? A 9200 is barely better than a GMA950, especially the crippled one that apple used, hell at least it has core image now, this is really an upgrade this GMA950 will work with typical OSX apps a lot better due to core image. The 5x faster CPU will probably make up for any minor difference between the GPU's. Come on apple wouldn't have done this if it was sigificantly slower for games. Besides this is not a gaming machine no low end machine is. If you are going to be gaming, neither the mac mini g4 or the core duo one will be satisfactory and you'd be silly to pick anything but an imac, which has a x1600 and that is a killer GPU. The main problem I have with it is I think it's a shame that the core duo has raised the price of the unit so much. Too bad there was really no other laptop CPU with SSE3 to use. Celeron M mac mini could have made it really cheap. Come on it's a budget mac, low price is the best thing for it and best thing for apple.
Although the optical out and gigabit ethernet are really handy additions to it, makes it useful as a cheap server or home theatre computer.
