I 've had one since release date a while back,
It worked as I wanted straight out of the box (good wifi browser with firefox).
Only thing I have altered is upgraded skype to latest version so it can do video calls (which needs an ever so slight single-line hack).
I end up using it in preference to my £1000 121" laptop most of the time
Only downside for me is the screen could be wider (wish it was 1024x768 so I wouldn't ever need to sideways scroll in firefox)
