Just been into town and got a clear plastic hard case, a foldable stand and a zip up cushioned case....all for £4!
The case is for a iPad 2 (sorry for swearing!) but with a very sharp hobby knife I was able to cut extra holes for the buttons and ports after marking them out with a sharpie. It's a VERY snug fit, but with a bit of shoehorning it goes in fine so now it'll stop sliding around on smooth surfaces when trying to type.
The pouch is a simple teflon school trouser type of material, but is nicely padded and the Extreme with case on slides in nicely with no sliding around once inside.
The stand is a simple chrome wire affair, but folds up nicely and slides down the back of the Extreme when inside the pouch.
Pics below if your interested....and where do you get all this lovely stuff for just £4? POUNDLAND!!! I'm in love with that place now!! I'm sure someone could make a better job of the cutting out (and taking the pics for that matter) but it only took me 10 minutes, and TBH I'm not that fussed...it works, that's the main thing!
