I still miss the old Stowaway keyboard: http://danbricklin.com/log/stowaway.htm

It would be awesome to have the same keyboard, but updated for modern devices. There's lots of cheap Bluetooth keyboards out there these days, but I've never seen one as mechanically elegant and nice to type on as the Stowaway was.

I still cling to mine, though the keys are a bit sticky these days. Haven't used it in a few years because it's not suited to (as you say) modern devices. But there doesn't seem to be any substitute, and I'm stumped as to why. If I can keyboard cases for an iPad for $25, I imagine the hard Bluetooth problems aren't so hard anymore, so it's a matter of making the hardware. But if someone thought there was money in it...

This is the key for me. I have a first generation iPad and a bluetooth keyboard. The only apps that I really use are Prompt (an SSH app from Panic), Pocket, and iBooks. It is an old iPad, but perfectly usable as a terminal, and I can spend all day in emacs with battery power left over to read articles on the way home.

Which Bluetooth keyboard do you use?

I use the Apple mini one. Good battery life and I'm happy enough with the feel.
