I'm still using an original IntelliMouse Optical 1.1a The plastic has turned brown from age, so I might buy one of these to tide me over while I apply some Retr0bright gel to the original. I wish they'd brought back the 1.1a. There wouldn't be any complaints from lefties, and the side buttons are large enough to not be missed by your thumb/pinkie finger. Oh, and impressive Rube Goldberg video introduction. Loved the "Portal" reference.
