I'm going to school this fall for graphic design and I can't afford an iMac. Anyway. Will the cheapest Mac Mini work well for use with mostly just Photoshop? I don't want to waste the money if it won't. Also would a 720p 42" plasma tv be any good as a monitor? I know it sounds ridiculous, but I don't have a lot of money to work with and it's what I have right now. Thanks for any help. Also since I'm starting in August I might be able to wait for a refresh.
