Waterfield have just announced the iPad Wallet - a case for the iPad and wireless keyboard. I like the look of that.

I've bought several Waterfield products over the years - mainly Cargo Bags and sleeves - and always been very happy with the quality and durability. Expensive, yes, but I think you get what you pay for. If you buy one don't forget pics and a mini review
