Regarding tablet
devices, I just ordered a Nexus 7. The reason I ordered it was because it is the least expensive
device I could find that's optimized for use with my newest RC quadcopter, but here's a video from Consumer Reports that speaks of it being better for the Kindle app than other tablets.

Thanks to
@garyoa1 (I think) telling us about Invisible Hand a while back, Invisible Hand was able to find me a better price than on Amazon, and then found me a $20 off coupon, so I was able to order a new Nexus 7 for $108, shipping included. I ordered it here:
Edited to remove link to dishonest seller, who sent me an email saying the item is out of stock, even though they still have it listed for sale at that price. I've notified Invisible Hand that the seller is a scammer. I now have ordered a used Nexus 7 on Amazon for $105.
