Putting aside the obvious issues with comparing a $100 device with something that costs maybe as much as $5, would anyone really use something like this? It seems to me to be a solution in search of a problem with a couple of nice features but I'm not sure if they're enough to make me change my habits. Besides, I can always just take a picture of my notes with my iphone and put them in Evernote.
If it is thin and light I would carry one everywhere - the way Kindles get carried around. I currently carry pads and paper everywhere.
However - I don't want features. I want a really good writing/sketching/doodling experience - something that an iPad cannot supply. The only feature I'd want is the ability to easily get my notes onto other devices
Why shouldn't we carry an iPad, a Kindle and a Notepad?
