I tried one, it looked cute, but it wasn't too easily controled, and I am looking for an alternative to a mouse, my hand gets cold and goes to sleep during a long session.

I bought one of those , my finger was too big for the hole, gave it to my 12 yr old daughter , she liked it but I found it hard to get used to using it. It didnt last that long , paid $20 for it , lasted 6 months. Unless youve got small fingers.......

Have any of you tried the Cirque type mouse replacer? It's a small pad and you just run your finger over it, instead of actually moving a mouse.
I've got one for sale if anyones interested. http://www.cirque.com/shopsite/cs_products/catalog.html
