This isn't going to be a big post or ground breaking, but I just wanted to talk and show you a cool little feature that I wasn't aware of until recently. Having written a review on the IVSO Wireless Bluetooth Keyboard for Nexus 7 last month. I found that for me the one problem I was left with to make it into an android laptop was the lack of a mouse. 
Micro-B Usb Otg
Initially I bought the OTG USB cable to allow my Nexus 7 to use jota USB stick as extra memory and for file moving. Then one day whilst having my nexus in the dock next to my PC I though what else can I plug in. Which led me to plug the mouse and to my astonishment it worked perfectly. Now having discovered this, then actually Googling it, I discovered I was nowhere near the first to find it out. None the less I found it useful to know. The mouse was the last piece to my puzzle.
I made a short video just to show how useful this can be.
For anybody that is interested about getting one of these little gems I'll leave a link to it here.
