I too had been lusting after the Que, thinking it would be perfect for scanned items; I didn't worry about storage so much because of the wireless capability (wifi and 3G for the very expensive model). Should have known how expensive it was going to be when they wouldn't ballpark a price for a year and kept saying it was for the "business" market. Still I was prepared to pinch some pennies and scrounge for eBay auctions for the thing, until I saw demos of the finished product which were as amazingly slow as the prototypes they'd shown months earlier. This would be almost tolerable if you were just reading through documents page-by-page, but the big eReader draw for me this academic is the ability to carry a reference library with you everywhere, where you can find the nugget of info you're looking for in a few seconds of "flipping around". I guess eInk is not up to the job yet, if it ever will be.
Mirasol might be worth watching down the road, but I've definitely got my eye on something with a PixelQi screen for my next reader.
Anything worth doing is worth doing poorly.
