My kid needs a new laptop for school. I figured he could pick up a less-than-a-year-old 13" MBP on ebay, get applecare, and he'd be good to go . But I noticed a couple of posts here about back-to-school sales . . . so now I'm wondering if we'd be better off just buying new. But it's June - are there really sales this time of year? And do they really always start on Tuesday? (I know Tuesday is new release day - I just didn't realize it's sales day also!) Look, when it comes to buying anything new . . . well, I'm a real newbie! (Don't even ask how old my laptop is!) So, if you can explain this to me r.e.a.l.l.y s.l.o.w.l.y . . . that would be a big help! I've already come across some great deals, including a late-'08 15" MBP (unibody) available locally (with about 9 mos. of applecare left), but I'm inclined to think that for a teenager, 3 full years of applecare is probably more important than gHz or screen size. Any advice would be appreciated! Thanks!!!
