The mini isnt designed to be a... hardcore gaming box, therefore a discrete GPU isn't necessary. If you require a bit more performance, GPU wise, than I'm sorry but a Mini is not for you.
For the record, the 9400m has been more than sufficient for anything I've thrown at it. Though that mostly includes 1080p video.
Throw a Blu-ray dump at it. I think you'll find it
less than sufficient. I certainly have done. And who said anything about "hardcore gaming"...?
The Mini is 'for me' in all sorts of ways. I love the design and the versatility of it, already. On the other hand, I become less and less interested in the narrow-minded attitude of certain members around here.
Before the 9400M was introduced, Mac people would say, "d'uh...!!! why would Apple improve the GPU? It's not a gaming rig. If that's what you want, go somewhere else...".
Bulls**t. Apple have now improved the GPU twice in fifteen months, and they've been promoting this new Mini with screenshots from Team Fortress 2.
Steam just came to the Mac, for Christ's sake - d'ya think this is all a coincidence...?! Video performance is clearly becoming an increasing priority.
All this, "if it doesn't do what you want, buy something else" talk smacks of people being unable and/or unwilling to debate the development opportunities of this great little computer. Mac gaming is on the march. A year from now, we'll see who was wrong.
I suppose I have to wrestle with my conscience in the meantime, and decide whether or not I can wait. There'll be nothing as pretty and near-silent running as the Mini, but maybe I can forgive that...
