First, let me start by saying I am finally switching after 6 years of wanting to. (Before, I was in school and my parents bought my computers.) I waited until after WWDC just to make sure no new iMacs came out, but since nothing did - I'm wondering if I should keep waiting of just buy now. I am generally a very impatient person, and I'd really like the iPod promo. So, to help me decide, how hard will it be to upgrade to Leopard after the fact? Should I go ahead and splurge on the 24"? I don't do anything intensive - basic computer stuff, photo editing and the occasional, simple DVD. Would the 24" be worth the added expense for me? Would you suggest buying now or is the current hardware on the verge of being completely outdated? Thanks for your help!
