Picked this one up for the Power Quality conference. It’s a wireless, handheld mouse called the Gyration Ultra GT. It has a range of about 30′ (most wireless mice go 3′ – 5′ max). It works on the desktop *or* in the air (gyroscopes or something). It’s pretty cool. And best of all, the mouse thing seems to work and be useable – which is pretty rare with these presentation tools. About $80…..
