Long Version:
For some strange reason? How about inking in chemistry, physics, or calculus & post-calculus classes while other people using regular laptops put them away. Perhaps I'd like to load up GIMP or Corel Painter and do a quick sketch and/or painting while out and about, but I just by chance didn't have a fully stocked art bag with me. Maybe instead of having to tote around a kindle, I'll just get PDF versions of texts that are no longer under copyright and save buying and toting around a second device.
Anyway, blog posts I read hinted that the T91 and the T101 were originally coming out together... then the T101 was delayed... then they pulled some Apple-esque magic on the T91 (stuff like internal battery, downgraded ink unfriendly screen, etc) and like many others I opted to wait...
Short Version:
Hell yes I'd be interested in hearing more about this... cause I had to skip the T91 after they nerfed it against us Tablet PC users. This is the closest to my dream netbook.
