Been lurking for a while but I had a question. I like to travel as lightweight as possible, but I also type A LOT of emails throughout the day so I end up having to bring along a separate keyboard. Is there any thing lightweight that has a keyboard solution built into the case? I started looking after seeing TouchFire on Kickstarter but I don't know if I want to wait till they ship, is there anything else that's already out or should I hold out till this TouchFire case comes out and see if that helps?
