Clever Mouse, with removable tail
Mouse-wise I currently use a Logitech MX700. It’s a fantastic 8-button (!) mouse. It’s wireless which is great, but uses its own wireless system – so requires an USB receiver/dock thingamy which acts as a charger when it get low on juice.
I don’t think I’ll replace the mouse until it’s broken. However, I saw something today that sorely tempted me to upgrade unnecessarily. (something Logitech’s Laser-guided mouse that looks like a sci-fi parasite didn’t make me want to do.)
You see I’ve always thought that the logitech dock-a-majig was a component too much – and it has a real usability problem:
When the battery runs low you have to stop using it while it recharges.
This mouse, solves both those irritations:

It’s a bluetooth mouse that assumes you already have bluetooth on your computer (so no receivers to plug-in) and when the batteries run low… you plug in a USB cable and it charges from it and acts just like a corded mouse!
(Now if only it had more buttons… )
