Based on the gimped gamut of the Retina iPad Mini, I bought a used Nexus 7 2013. Talk about a cold shower. Don't believe all the talk about Android catching up to or surpassing iOS, it still sucks.
First the good: After downloading a few apps, I can wirelessly transfer files between the Nexus 7 and my computer over my local WiFi network, both ways. The Nexus shows up in the Finder to drop files directly on it, or I can go to a shared folder on my Mac from the Nexus. I live in a rural area and am stuck with cellular broadband, so Apple's solution of wireless syncing on some remote server is worthless to me. I know there are convoluted solutions for iOS that involve pointing Safari to a web address and downloading files over the local network, but the Android solution is 100X easier and just works.
Now the bad, awful, abysmally worthless, and comically stupid:
The Nexus 7's reader app doesn't work. Well, it does, but it will only read crap you download from Google Play. I have thousands of books and articles on my Mac and Nexus cannot read them. But there are 3rd party reader apps for the Nexus 7, just use one those, right? No, they all pretty much suck. Most do not have an offline dictionary, and the few that do have poor definitions and a clunky lookup interface. Highlighting a word is hit or miss; they don't hold a candle to iOS ability to highlite the word you touch. Formatting is lame. Performance is also an issue, with constant hiccups in the display.
Finally the difference between 7" and 7.9" is larger than it seems. Browsing on a 7" tablet is frustrating.
So, while I find the Retina iPad Mini's gimped gamma frustrating, Apple still blows away the competition on the user experience. File transfer is a weak point, but actually using the files once they're transferred is awesome.
