I asked CS if I had a faulty one, as I had a couple of lines of pixels across the top. They said yes, and arranged for it to be collected. They asked me if I wanted a replacement and I was tempted. I loved the look, but the other niggles swayed me against it. Very slow and blurry webcam, track pad for curser was all over the place - kept accidentally shutting off when I tapped it, was slow, Windows kept freezing and rebooting, battery life was terrible - they claim 5+ hours, I got max 3 usually 2. Maybe these were all problems related to a faulty machine. I did look on HP's site and found I could get it cheaper there, dithered about that for a while. In the end I went to Acer Direct and got a gradedA1 machine for £199 that was better spec. Bought a skin to make it beautiful and I'm happy.
I think I recall Piecan having similar problems, try looking at other threads about it.
