I'm sure that your estimates are based on facts and numbers so what is the consumption of an ARM processor? If we know that then we can work out a rough estimate on the overall consumption of the device.

To not mention the disadvantages of e-ink and the advantages of pixel qi is also very unfair. I don't think that people went mad for no reason and decided that pixel QI, mirasol and liquivista are the future, they must have pretty good reasons to make such claims.

Never mind jetbook and e-ink for a moment. If a 10 inch pixel QI pulls out 500mW then a 7 inch would consume roughly half as much? Let's say 250-300mw. Now is that any good or should we just loose all our hope for a better bang for our money?
