When I goes out to Aaron’s and puts in your zipper code thingie I don’t get lots of options and none of ‘em is a Mac. The HP 15.6” Windows 8.1 Laptop looks to be the lowest on the dollar-evolution scale and should do what you want, expecially if you can get them to not put Total Defense Security on it.
I don’t see any good tablet options.
If you could get one, I’d suggest looking into a Chrome book except you don’t like Googles knowing what you’re up to.
