IBM Keyboard with "TrackPoint"
It's a bit spendy.. ok.. it's absurdly over priced... but if you can find it elsewhere this might be a good option http://www-132.ibm.com/webapp/wcs/st...3644&storeId=1
It's a mini keyboard with one of those little nubs like a laptop has..
I've been trying to find another IBM keyboard.. it was wireless and had handles and a thumb thing that worked like one of those laptop nubs.
I saw it at a store a while ago for about $65. Why this other keyboard that is hardwired is retailing for $155.... man I wish I knew.
