Here at the GBM Summit, we’re talking Tablet PC, UMPC, and of course Ink and Touch. Well, you all know that Rob bought an iPhone. Earlier today I posted about the alpha release of a new Inking application, Sketches, for the iPhone. Being the discoverers and bleeding edge fools we are, we made Rob install it on his iPhone. Well, here’s a quick video of Rob demoing Sketches on his iPhone. If you’re headed to the meetup tomorrow, or checking out the UStream feed, you can see how well, (or not) this works in person.
