The MoGo is a portable mouse with a twist. It's Bluetooth compatible, so is able to connect to compatible laptops without needing an extra adapter. And once you've finished using it, you simply fold it shut and slot it into a PC Card slot, where it's both secure and receives power to charge its internal battery. Admittedly, it isn't comfortable to use for hours on end, but it's good enough for the odd job you can't manage with a trackpad. We experienced no problems with battery life, so if you're looking for an incredibly light mouse that can be used just about anywhere the MoGo is a good, if expensive, choice.
