I saw this on MacNN right after my post. Their short video (commercial really) is pretty cool. I'm not the target audience for this kind of device, I wonder how the real artists (or other potential users) feel about it. The eraser was a nice touch too.
I guess what I'm thinking is, IF Apple does a larger iPad there would have to be a compelling reason for it to exist and thrive. My speculation was that it would appeal to artists and or people who deal with paper docs for a living. The latter being real estate, lawyers... whatever. I belong to neither group so I'm not sure if that's even realistic. I remember buying a house, car, etc where there's just a stack of paper. Initialing and signing all over the place, this is what I think could be done better with a larger tablet.
The group I do belong to is the one where my eyes aren't what they used to be! I use an iPad 3rd generation at work and it is adequate. A larger display would be great too. So would a simple calculator that I could pull up without leaving my current app. A floating calc would be nice :) that way I could move the spreadsheet around and do math as needed. Sorry, went a little OT..
My current set up works fine and a larger iPad's weight wouldn't be a huge issue as my iPad stays in a stand for 8 hours a shot, so I'm not holding it. But that's just me....
