Disclaimer: The nice folks over at Maglus sent me a sample for test driving the brush tip.
I still believe the sweet spot for using mobile devices to paint on is doing quick sketchy pieces. In this one I am using the Maglus stylus with the brand new brush tip accessory for the first time. I was always a bit sceptical about the skeuomorphism that using bristles on a screen seems to be to me, nevertheless I gotta say no other tip has less friction than this one. I much enjoyed it as well as typing a cool word like skeuomorphism. There, again!
