When I was playing with it ( a few hours worth),my test is to browse to forums, and yes thte work prediction was very good, in fact you get that red line squiggle under words like a normal browser so you can click back and select the recomended word. Liked its style very much.
have you found a way to make text on forums smaller ? like you look on ocuk forums and threads are written with big font while columns next to it with small...
cant find a way around it...
