Marco loves Studio Neat’s Cosmonaut stylus for iPad.
I’m intrigued by it and I’d love to try it out. I’m still looking for the perfect stylus for sketching on iPad, and this looks like it might be really good. Like Marco points out, the problem is that because they’re all closer to pens, you naturally want to rest your hand on the screen—which doesn’t work out so well. A second, slightly smaller, issue is that the foam tips (along with the capacitive touch screen) provide an inconsistent point recognition, so you don’t always know where your stylus will draw on screen when it touches down.
The Cosmonaut looks to solve both issues. The first because the Cosmonaut is more like a dry-erase marker, so you’re less likely to want to lay your hand down on the screen, and the second for the same reason—you’re treating it like a marker, which inherently doesn’t have very fine control.
