Not that I recall seeing (other than never having a problem using a Palm TX prior to the N800). I didn't necessarily mean that I am only considering stylus based UI's either.

For instance the Touchbook discussed here: http://www.internettablettalk.com/fo...ad.php?t=27245

With the larger screen at the same resolution, using an onscreen keyboard similar to the current stylus keyboard or the matchbox keyboard becomes much more feasible. The keys would be almost twice the size. Thus, much easier to hit accurately. There are obviously some downsides as well. However, based on my needs/wants, price, and availability, it could well be a contender for my money.

I'm not opposed to a finger based UI. For instance I think many of the current crop of touch screen phones benefit from having a finger based UI. It seems that the more complex a task the phone is required to do, the more likely it is to have a stylus to allow for efficient operation, which is different from easy operation.
