Don't paint NVIDIA in rosy colours they're not that good. I have issues with both their blob and the free drivers. Try switching between displays several times in a row usually after 5 switches or so you'll get some error message with the blob (or crashes occur if you use nvidia-settings), and you just get crashes with the nouveau drivers. Also crashes at other times. If you want a stable laptop and use external monitors avoid them.

Oh, and OCZ SSDs? Seriously, you don't have to look far to find advice to avoid those. Try Amazon reviews.
