Nexus 7 2012
If you're really not looking to spend a ton of money on a 7-inch slate, you might want to take a look at the aging Nexus 7 from 2012. It sports some decent specifications and recently got upgraded to Android 4.4.4 KitKat. It's also available for dirt cheap through some retailers.
Google's Nexus 7 2012 is only going to be attractive to those that don't want to spend serious money on their next slate. It's an aging relic but one that could run out of steam soon thanks to Google's 18 month software support rule. Still, we've seen it on sale for $100 or so in recent weeks and that's pretty good for a tablet of this caliber.
Take a look at it. Its price alone makes it worthy of your time.
