You know what I want Apple to do for the gamers.
Just give them a MacPro for around $1900 base configuration like the PowerMacs back in the day. I got my dual core 2Ghz late October 05 for around $1800 ($2000 regular price) and I would never EVER get an iMac to play serious games. Even now I would just have to suck it up and get the MacPro. The iMac wasn't made to handle serious games until you get up to the 24" model and you still can't upgrade any parts down the road.
The iMac is also a machine made for people that aren't too interested in upgrading in the long run since they will be running apps that depend more on RAM then on graphics.
My girlfriend wanted a new desktop that could run Sims 2 and probably the upcoming Sims 3 so I informed her to get the 24" since it will have a much better graphics card and screen, and since everything else she will be doing other than the Sims will be "high end" teacher work (Excel) she wouldn't need much else.
Gamers... I don't see a new Apple gaming rig... I see better and more upgradeable iMacs (upgradeable to a certain extent) and I see cheaper more affordable MacPros. This headless tower thing is the past, the all-in-one with laptop parts and desktop HDDs is the future.
