A and C
I agree with all of your comments.
I have seen IO540's Motion computer in action which is no better (or worse) than my Lifebook, both of which mirror the comments you make.
I've got all the Jepp plates on the MFD, readable in direct sunlight, powered by the aircraft and with a nice green aircraft postioned on the plate God willing just where I am. It takes some beating.
However, I gather the new eBook is not trying to compete with either PDAs, notebooks or tablets. The screen uses a different technology that I am lead to believe is more readable than paper, even in sunlight. The battery will of course go flat but last a great deal longer than most of us can sit without taking a p!
I just wondered - it might work. Interested to read a few comments along the lines that it would appear to not suffer from the limitations you have so well outlined.
Any one used one?
