Forget DSLRs: Canon has a new gizmo for us. The "industry's first" mouse with a calculator and numeric keypad is a 1000dpi optical USB mouse that flips open to a full keypad and 10-digit LCD screen. And yes, you read that correctly: the LS-100TKM is from Canon, not Brando. Strange... but if you're an accounting type who needs a calculator and keypad for your notebook, this might be the ticket. Available in Japan at first for around $32, in early July. [Impress]
The only problem I can see with these is that when you start pressing keys on the calculator, your cursor will move on the screen, dumping entered numbers all over your doc/sheet. Does it have an emergency brake to set to keep your cursor where you place it?
