I've never owned a Mac computer, but I've always wanted one (but couldn't afford one since I just graduated college). Anyways, my work has a computer purchasing program were they sell their older computers to employees at a discount, and this time they are selling a few iMac's + random PC's. I put my name in the drawing but wanted some advice: They have two late 2006 20" iMac's with 10.5OS for $100 (2gb memory, 250gb hd) One early 2009 24" iMac with 10.5OS, 2gb mem and 1TB hd for $150 Two mid 2007 24" iMac with 10.5OS, 2gb mem and 350gb hd for $125 One iMac G5 with 10.5OS, 1gb mem, 250gb hd for $50 None of these have any other software that comes with them. My question is which one should I hope to be drawn for? How difficult will it be to get word,excel,etc for these older machines? Is the OS upgrade able from 10.5? Thanks!!
