So far from what I've read in reviews:
Delivers high performance and stays cool as well as quiet, however the keyboard is a bit awkward to type on. Also, 1 1/2 - 2 hour battery life and it's heavy.
I'd say about 15% of the time I've read a review where someone had to exchange their new one for another new one because of some awful fatal error that varied from case to case but mainly dealt with random crashes linked to the BIOS, which isn't too much to worry about if it's updated.
I don't mind the battery life, the weight could get annoying though. I'm used to annoying keyboards, also, that that doesn't phase me.
Considering that this is their latest model, I might wait for the next one to come out so this drops a bit in price, especially since I don't need the laptop asap. I'd still like opinions though.
Oh, also, they load it with bloatware and don't give you the OS disk, so unless you burn the disk to reinstall the OS, removing said bloatware could be a little tedious.
