I have the first generation Ipad and a Zaggmate case, I could not recommend it much more, it's a total laptop killer for me.
The Zaggmate case is a total boss, has the same silver finish as the ipad so makes it look like the coolest laptop and when you sit it in the upright stand in the case, the case turns into a fully functioning qwerty keyboard, which if you use it for writing for relatively long periods, as I do, is a complete life saver.
