trust me! all the capactive styluses are nothing more than gimmicks! pressure sensitive or not! they worth nothing without accuracy!
though, I'm waiting for ipen2! because it's the first pressure sensitive ACTIVE pen for ipad! I believe this one has a LOT more potential than all styluses out there! not to mention it works on all platform (windows, linux, OSX, iOS, android, etc)
Can anyone link me or write me a good WORKING stylus for iPad drawing?
