I finally received my order from Amazon. I received a new cover that makes my Nexus 7 even more portable when I don't need the extra keyboard.
And finally, I got the usb adapter for the keyboard.
It worked just as advertised. I just plugged it in to the port on the Nexus 7 and into the usb cord of the keyboard, and it worked automatically. No need for me to change any settings.
But I like the change, and all that matters is me, right? :-)
Now time to get ready for work. The phone's been ringing, so it's gotten pretty busy.
