Congratulations on a very complete Duo starter kit there!

I don't think there is much I can add that beachycove hasn't already covered. Except to say that out there somewhere on the web, there are, or used to be, directions for cleaning and repairing Duo keyboards to get the best (least worst?) possible performance out of them.

And if you get completely sick of the keyboard, you have that nice Wacom there for a Duo tablet hack!
