try this, the HP 500 Slate vs. iPad...and while I feel it's a couple hundred too high, it's a stark contrast to the IpAD as it's certainly an actual REAL COMPUTER for less than the best ipAd
And it's real...yes batter life is not ideal but there are likely extended life battery options...it fits the need of a very large part of the slate pc user segment.
I would still prefer a 12" panel but maybe they too are waiting on Mirasol...or I am not sure why freak Pixel Qi is not gaining traction. Someone needs to be first...
My point in posting this is that if ereader device makers don't vastly improve their underlying OS and software, it will be devices like this Slate PC that will grab the business, academic as well as home researcher. People today are sort of tired of work around and as a productivity tool a 9"-12" slate with a Wacom or N-trig digitizer is a winner if it has specs at least as good as the the HP 500. But as I said already it's not perfect but for me it would be a better option now than an iPad.
