> It occupies too much territory already covered by > smartphones, PCs, laptops and traditional media. For me, the question isn't whether it covers territory already covered by existing electronic devices like netbooks or what have you, but whether it covers a significant amount of the territory covered by _paper_. Can it substitute my A4 notebook, or my diary, that's what I want to know. It won't be the same, but will it be as good or better, all told? As a substitute for a PC, netbook or smartphone, it's compromised in important, possibly fundamental ways. I don't know if it is similarly compromised as a paper substitute. If not, mass market acceptance awaits.
