How much use can I expect to get out of a refurbed off-lease (probably school) Feb 2008 white Macbook? I've been mulling picking a couple up for my two daughters who are familiar with Macbooks from school, but they're still about $500 as refurbs on eBay. Considering I could get them a BRAND NEW low-end Windows laptop, I'd expect at least 3 good years of trouble free use out of them. Is that realistic? I'm all Mac except for the 2 retired laptops they're currently using. One is REALLY old to the point its frustrating my daughter out of using it. It is a Celeron M 380 which I can't find much info on. I found an M 410 on Passmark and the score for that is like 365 vs. a 1362 for the 2008 Macbook. The other is newer... its some kind of AMD Turion x2 64 processor. Its useable and the problems are more typical old windows laptop stuff, though I restored the OS recently. Would a 2008 Macbook even be an "upgrade".
