I've been using the two for a month or two now for work notes (everything I do has to be documented in case of Freedom of Information requests). It's really good, but the lag between screens is just enough to be annoying.

I tried the Boox Air, and it felt like trying to write on an overhead projector (for you youths, it felt like writing on a piece of stiff plastic). The one thing the remarkable does extremely well is simulate the actual feeling of writing on paper. That is very, very nice.

I wish I was able to modify my tablet, because there are so many super handy things you can do with it!
