I would actually consider buying one if it could run a proper OS (e.g. proper Windows or proper Linux). I have been looking for a device for ages I could use for reading e-books in bed before sleep (notebooks are too "heavyweight" for that and I think that the Kindle and other e-book reader hardware are way too underpowered and painful to use).
This one looks like it has just the right dimensions and a responsive iPhone-like touchscreen would make it really easy to use for reading.
