The original one still works and there's nothing really wrong with it. But it just got too slow due to all the memory demands of modern applications these days. Also, it was burning my legs! The new MacBook Pro is much slimmer, faster, uses SSD hard drive and runs very, very cool.
What bums me out is that the 16" version just came out...oh well, maybe next time.
I got an old Pentium I need to get running so I can use my old negative scanner. I don’t see having to ever get new hardware unless it wears out.
