I just ordered one EE and waiting for a friend to ship it to UK. I had researched a lot and decided to go for this instead of an Ipad.
The main reason I choose this is the e-ink and the android OS.
The main problem of this device is I think is missing a proper keyboard in landscape mode. I suggest to get something developed like in MSI prototype.

either to have a black and white keyboard on the e ink screen or a color screen keyboard in landscape mode and write on the black and white. this will be of great help for students and writers. No other device will be needed.
