I'm looking at a 1st generation MacBook Air. I know this model has had lots of issues, but would a macbook air that's refurbished be maybe more reliable? Would it be a good idea to get a MacBook Air? I know it has a reduction compared to regular Macs but I do like the thin form factor. I don't mind the lack of ODD and other stuff, but would it be a good idea to spend $100 more on a Unibody? I really do like the MBA.
