Like ohbalto says, a 10" mac with the iPhone OS (3.0 most likely) would have enormous potential. It is already a stripped down version of OSX and the API is actually not that bad to program for, I could definitely see it being very functional to use. My only concern is power and weight to be honest. Would I use it as an ebook reader? Certainly part of the time I might, but I'd still prefer a simple e-ink display for that. No real details on the screen have been released as far as I know. We know the size but we don't know the type, it might be a reflective TFT for example. Only time will tell
