HP recently released, an 8-inch Android tablet with a super-high-res display and Nvidia Tegra 4 processor for $329. The high-end specs petered out when it came to the OS, however, as it ships with the older Android 4.2 Jelly Bean.
If you want to be totally up-to-date, HP has the answer for you -- though it will cost you a little bit. The company has stealthily launched the Slate 8 Pro Business edition, which is similar to the non-Business version save for one key difference: It runs the latest version of Android -- 4.4, or KitKat.
Otherwise, the Business model appears to offer similar hardware as the consumer model, from the 1,600x1,200 Gorilla Glass 3-protected display to the 1GB of RAM to the 16GB of solid-state storage. Both feature the Tegra 4 A15 processor, integrated Beats Audio technology, and a black front face backed with a white back panel. The only other notable component distinction is that the Slate 8 Pro Business has built-in NFC capabilities that the other version lacks.
The final difference between the two tablets is in the pricing. You'll pay an additional $20 for the Business model -- call it the KitKat surcharge. While adoption of the newest Android version is growing, it still only accounts for. Perhaps the Slate 8 Pro Business edition can nudge that number further upward.
