Both me and my wife bought Macbooks at the same time and have encountered NUMEROUS mechanical problems with both.I've sent my computer in twice, for problems, the second time I got a completely new computer but still have to put up with problems. My wife has sent hers in twice as well.We are totally sick of the hours we have wasted with their customer support pretending that the issues we are experiencing are something they've never heard of when their are websites dedicated to these Macbook problems.So after spending a lot of money on the laptops we've finally come to accept our keyboards occasionally not working, trouble waking from sleep, but just recently both our screens have started flickering... I've just got to endure loosing my computer again to apple to fix... Once my warranty runs out I know I've as good as lost this computer.I loved Mac but after all this all I can say is do yourself a favor and avoid this laptop.
