Got my stylus. The app isn't bad, but yeah, it is laggy enough to be kind of annoying, and you can't rest your hand on the screen, making it hard to take notes. Very cool for drawing though!
The stylus was cheap, and worth having I think, at least for drawing and things like that. There's a whiteboard app too- not scaled for tablet yet, but I saw a note saying they have a collaborate version, which seems pretty cool.
does seem a little strange to me that there's no real good note taking app. Back in the early PDA days (my dad's a tech geek too, I got his hand me downs, I had a Newton and early model Palms and such) it was one of the big features!
