I found one 1.83Ghz CoreDuo, 1GB, 60GB white MacBook on CL for $750. It's still covered in warranty and I can purchase apple care for it. I looked in person last night and it's in excellent condition and everything works perfectly. Is it a good deal for the price? The owner couldn't find the reciept, will I have problem activating the apple care I'm gonna get from eBay? Anything major I should be careful about that first gen. MacBook? I've heard it runs fairly hot. so have anyone used CoolBook? Wondering whether it works well or not. Thanks guys!
