I hope that you make some real progress today....I am not trying to be pushy, but you asked, so let's be sure that you are not stagnant.
sorry about the car, I have a Nook HD that I used with good internet access (it holds Google play), before I got my tablet. Ask your young co-workers, everyone has a tablet these days and lots of free Wi-Fi.
I have the Galaxy Note 3 tablet with the S-Pen. there are much cheaper models too (ask Itchy).
How about giving yourself the date of July 4th to cut off the internet...Independence Day!
