I tought it would be good thing to take notes in school with stylus and typing should be fast too with the big screen. So do you think it's practical to buy this or just expensive, cool, shiny gadget?
Certainly better than my Hero(-.-).
But besides that, I have never found taking hand-written notes to be convenient. That's why the computer revolution has served me so well. I'd much rather sit in class with a keyboard in front of me and dash out my thoughts that way. Either paper and pen for me or give me a keyboard.
But if you need an excuse for an expensive, cool, shiny gadget, then I have no objections whatsoever.
