This appears to be something that I had been waiting for but the video and the website do not provide enough information to address all your questions. It sure is a unique artist paintbrush stylus for the iPad made with a long handle and soft bristles, but is it pressure sensitive? Is it going to work with all those paint and sketch apps out there or would come with it’s own?
The information is very sketchy and I see a slight lag in response (may be just me!) in that three seconds demo shown in the video above. Available February 2011 so meanwhile enjoy this and yes, I hope Wacom is going to wake up soon.
