I have the same opinion, that sliding and rotating the cover is easy and that pushing the cover up with the thumb to get at stylus, is also quite easy.

I agree that with the modifications to the case it could be made much easier (Shame not captured and put right before release to public), however if using the unit to surf the net for any length of time discarding the casing altogether is a better choice as its then much lighter to hold in one hand with the stylus in the other.

What we could do with is perhaps a forearm/wrist attachment, that somehow provides support to the wrist to whilst presenting the 770 in a very comfortable palm position, which allows thumb and fingers of hand access to buttons etc? (even without the case the 770 does not feel very light over time)
