Can somebody explain why they need to be typing on tour? I can't see it. I understand why one would make notes of their journey, but I have a tiny notebook for this and a small pencil. If I want electronic notes my blackberrry serves me well.
Just reading all the suggestions about keyboards, laptops, tablets, netbooks seems to be a complicated expensive process compared to a little notebook that you can scribble in and even make sketches. On one tour I printed my maps out with one side blank and used this as a notepad. Worked very well.
Oh and nobody wants to nick it.
