Hi all, Just looking fro some general advice here. I'm buying a Mac for my parents, and struggling over whether to buy a Mac Mini and an external (likely non-Apple) display or just to bite the bullet and buy a 20" iMac. I'm sure that an external display will WORK fine, but will the screen quality (regardless of what I buy) be unbearably and noticeably different than an Apple display. Can anybody recommend a good 20" display that will be compatible with a Mac Mini. Alternately, can anybody tell me why it might be worth forking up the extra $$ for the iMac. I know what the differences are spec-wise, but if there's something glaring I should know, I'd appreciate it. I'm trying to be as economical as possible here. Thanks!
