I have been eying the Freedom keyboard and the Stowaway one. If you are looking for something cheaper, Brando Workshop appears to have a few Bluetooth models dirt cheap ($56-70). I am curious to see what people think of their Bluetooth keyboards, as they are the least expensive models I have found. The "Mini" looks to small to really be practical, but I bet I could hit a pretty decent clip on their "Smart" model, especially after many years of working on HPCs. I bought my aluminum case for my 770 from Brando and am very satisfied with it.
