Ten One Design's Pogo pen — $19.95
Every now and again, I admit that I use a stylus with my iPhone and iPad. Especially, with the smaller screen. There are a number of apps that place links and other clickable buttons right up against the sides of the screen and my pudgy fingers can always accurately hit them. So, a stylus really helps. I use the Pogo pen from Ten One Design.
I've used several versions Ten One's Pogo line, including a small one that clipped to my phone. The Pogo pen stylus was recently redesigned and it's even better than before, now letting users replace the tip as well as remove the clip. It's a very clean, strong design.
