I'm thinking about the N770 deal but have read quite a few posts of the infamous WSOD. I'm debating between the 770 or 800. I could definitely use the cheaper price and the better aesthetic design. However I'm quite concerned that I'll be spending $140 on a lemon. The only reason for me to get the 800 is because of the potentiality of the 770 to die on me after a few weeks. Is it a common problem?
