In Pictures: 20 best tech devices of 2012 (so far)

The year is just a little more than half over, but we've already seen an explosion of innovative tech. Here's a look at the best of what is out so far in phones, tablets, HDTVs, cameras, and more.

Google Nexus 7

This highly anticipated 7-inch tablet is poised to compete against Amazon’s Kindle Fire. Made by Asus, Google's slate comes with a quad-core Nvidia Tegra 3 processor, an HD display with 1280-by-800-pixel resolution at 216 pixels per inch, a 12-core CPU, and a 4325 mAh battery that Google says should give you 9 hours of HD video playback on one charge.

The tablet also sports near-field communication technology, as well as GPS, Wi-Fi, Bluetooth, and a 1.2-megapixel front-facing camera.
