Three great minds then - maybe all the great minds are in the UK then? (only joking)
I'm waiting for my MCover to arrive as then it won't be in a book type cover. I didn't want it to be completely 'naked' as I throw it in my laptop backpack for the train journey to and from work. But I can't use the buttons on the left with the book cover whereas with a skin or single cover (or a flip cover I guess) I can do either with right hand (on train, station platform, etc.) or left hand (usually when eating dinner with the right!).
