The system is quite bulky and heavy. The folding and unfolding is done correctly, but it either does not slide perfectly. The keyboard is usable, relatively nice, but not great either.
The set is thick and heavy. Usable, certainly. But it breaks the point of having an ultra-thin and ultra-light tablet if it is to make it a big netbook. Personally, I returned and I'm going to go on a standalone and easy to handle keyboard.
