I would like the capability to play games.. at least play the addons for half life 2 and maybe some sc2... however the price point is kinda more important that this. I am so busy and have so little time for games that paying an extra big sum for the capability seems silly. Also, if I decide to drop in a solid video card in the future, shouldn't these machines be plenty capable?

As for audio/video stuff, I couldn't care less. So long as it can play pandora/itunes and dvd/netflix I'm happy.
