In an effort to make more out of my iPad, I downloaded Noteshelf (other apps are available!) and bought one of these to replace my work notepad and biro.
It's still day 1, but I'm very pleased - it's like writing on paper but I can undo and rub out mistakes! The stylus feels very natural and I soon forgot I wasn't using the old pen and paper.
I think a good app helps loads.
Funny, the iPad responds better to the stylus better than my finger but I wouldn't use it like that all day.
I bought a Wacom Stylus as various reviews rated them best, I know you can get much cheaper but no point being disappointed with cheap rubbish :)
Is it worth it? Yes, so far! I'm going to make a real effort to use this every day, so far much more fun than the old boring biro!
