Of all the online stores where you can find cool tech gear one of my favorites is ThinkGeek. It has all sorts of gadgets and some of the coolest geek toys on the planet. ThinkGeek has a bunch of stuff that is designed to work with Apple products and the latest offering is a new case for the iPad that has a Bluetooth keyboard inside. If you want to use your iPad like a netbook on the go, this is the perfect case for you.
The case is covered in black leather and it has a BT keyboard that is specifically designed to work with the iPad. The keyboard has a number of keys specifically linked to iPad functions like home, volume, search, and iPod functions. The only downside I can think of is that the keys look small. That said, they are sure to be better for lots of typing than the on screen keyboard.
The leather case has a magnetic flap closure and can be used to prop the iPad up in various angles for working or watching video. The case with the iPad inside weighs 2.75 pounds, the keyboard is powered by an internal battery that charges via USB, and the charge cable is included. The battery is good for up to 90 hours of continuous use so you should be able to go a long time on a single charge. You can order the thing for $59.99 right now.
