You have a couple options as I do use the Stream 7 as my primary machine at home. I have the MS Wireless Display adapter and use a bluetooth mouse & keyboard. If you look at the link Jiffybag posted, I have the OTG USB Changing dongle and use that for any USB devices I need.
I have found that generally, if you want to go this route, that the Plugable Pro8 device would be the better, cheaper route. If you don't want something that big to lug around with you, than you can do what I've done.
I will say that the Stream 7 definitely cannot handle streaming video/games, etc to the MS Wireless adapter, but does work well as a monitor for less graphic intensive tasks.
