Bluetooth keyboard/mouse for android (Nexus 7)

I was thinking about trying out a physical keyboard/mouse for Jump desktop on my Nexus 7.  I am controlling a Win7 machine, so it is important that the keyboard supports windows functions.  (has alt/win/fkeys)

Here are a few keyboard/mouse combos I am looking at:

Maybe though, it would make more sense to look at a larger size.  I'd like to know if anybody has had success with this on android.
