Has anyone used one of these stylus pens with an iTouch/Phone?

[rgG]

I did not know that there was a stylus available for the iTouch/iPhone, but here one is. They have a video showing it being used with an iPhone and it appears to work as advertised. It seems to have a rubber tip on the pen. Has anyone ever used one of these or something similar? I find the iTouch/iPhone's virtual keyboard hard to use, so this might be a good solution for me, if it works like it is supposed to. Here is the link:
