The only two complaints I would make is, first, it is virtually impossible to type quickly due to the tightening keys (itself conditioned by the width of the tablet itself: here physical restraint and not a design error). This is a handy device to write an email or a short note, totally unusable to write a chapter of a novel, a report, an article or a rather long letter. Expect the purchase of a second keyboard "house" if we want to play Stakhanovists Qwerty.
The other complaint is the lack of a "glide pad" or "trackpoint" (so elegantly Clitostick called by some). the incessant movement of the hand between the keyboard and the screen to activate the pointer is not really ergonomic. But again, this is an extra keyboard practice during a trip, and that will be advantageously replaced by a more serious set "home". Microsoft Wireless Entertainment 7000 Genre which is perfect for this use.
Note that in "portrait" position, the tablet tends to swing the at least éfleurement. This problem disappears when the screen is in the "Italian" (landscape for IT-cians)
