Anyone thinking of a case for their Pro, just took delivery of a Manvex case. Black and grey leather, £30. First impressions, feels very high quality. Surface fits snugly, has cut outs on the sides and top for gestures dragging into the screen. Closes magnetically (quite weak), but has an elastic strap to keep it more secure (which is required if you have the type or touch cover attached as the magnets don't work with the cover in the way). Makes it a little tricky to use Chrome as the leather in the top left makes hitting tabs a bit more difficult but still doable. Built in stand system seems solid so far and gives you a few more angle options than the built in stand.
Pretty good all in all.
