I've used one that worked like a pen. It had a small plastic disk at the tip that swivelled so it would keep contact and not slip. I never found out who made them though. It didn't feel like a giant cumbersome crayon though.

I've used one of those and I found it to be an equally terrible experience. Not sure if they fixed them, but the first few generations of that product left scratches on the screen.

Recently came across this on kickstarter : http://www.kickstarter.com/projects/227221698/truglide-apex-... - says it has 2.4mm tip (also says 5mm some other place - but that too is equally small) This one is w/o the "disk"
