Some say they are very fragile, and break off / take damage very quick and easy (considered I'm not thát careful with my stuff either hehe). The hand-touch feature is not nearly as good as it is advertised (often inaccurate or fails to recognise your finger movement at all) but the pen-touch versions, on the other hand, do very well. I do want a hand-touchscreen instead of just a pencil, so this inaccuracity is something I take in my concideration.
My dad has a tablet notebook and although it looks fragile, it never broke. Still, you do have to be careful with it, more careful than with a normal laptop. As for the inaccuracies, those critics are probably exaggerating. The accuracy on the tablet my dad has is very good and honestly it's a pretty old tablet notebook (read: year or 2 old).
They are great to work on, the only thing I didn't like was the fact that it was a 12" inch or so screen. WAY small.
Apart from that, pretty cool computers. HP and Acer have a pretty long history making them and generally those are very good.
