What I want is the features of the Oynx boox (WiFi and software support) in the iRex 800 form factor.
The fact that iRex have had the Wifi experience with the Iliad and tried to go down the subsidized 3G market (and failed badly in Europe) with the 800 is irritating as I would have bought an Iliad if I had thought that it had not been abandoned. I hope that a SW version is brought out.
The fact that the 800 is approx the same length of boox and only just over an inch wider, (with an 8.1'' diagonal screen) is stunning. The Sony 900 I think is too long and too narrow.
I would prefer a thicker unit to handle the battery and pcbs than have the current market format of a thinner unit with large bezel area at the bottom of the unit.
