I was wondering If people prefer to fold the keyboard all the way back behind the unit when using the SP3 like a tablet, or just detach the keyboard altogether. I think it feels kind of funny to be crunching the keys with my fingertips, so I like to detach it. I know they show attaching and detaching of the keyboard anytime in the SP3 commercial, and I haven't read anything otherwise, but there shouldn't be any issues with attaching or detaching the keyboard when the SP3 is on, right????
