I really want an iPad mini.
The only reason I upgraded from an iPad 2 to the iPad 3 (or whatever it's called now) is because I could get LTE tethering from Verizon, which has been a gift from the universe on the few occassions that I've needed it.
However, ever since I got the first iPad and gave my wife my first generation Kindle, I've missed the smaller form factor of the Kindle eReaders.
The iPad mini looks like the perfect device, especially with Verizon LTE.
With all that said, I need an iPhone 5. (Really.) It's the only iPhone that we're missing for the purposes of software testing.
Plus, with the quick and unexpected release of the iPad 4 (or whatever it's called), the resale value of my iPad 3 isn't looking so good, so I'd take a hit on the upgrade.
The iPad mini is definitely my next iPad, but by the time I'm ready, they'll probably upgrade it to a retina display, anyway.
