If you really need a physical keyboard to work with the iPad, you might want to try out Logitech's new Ultrathin Keyboard Cover, because it makes it easy to bring one along without adding any much bulk to the tablet.

The $100 Bluetooth keyboard—available sometime this month will promise up to six months of battery life as long as you're not typing more than two hours per day. It will also magnetically attach to your new iPad or iPad 2 like Apple's Smart Cover. [Logitech]
