In the race for the best 7-inch tablet, the Amazon Kindle Fire and Barnes & Noble Nook Tablet have zoomed past the competition with sub-$250 price points and well-rounded reading and app selections. But a third competitor with similar tactics has just suited up to take the track: Kobo’s Vox. Kobo itself might have just been acquired by Rakuten, but that isn’t stopping the company from forging on with its own $200 Android tablet. Now, the Vox isn’t as well spec’d as the Fire or the Nook Tablet — it’s only got a 800MHz single-core processor and 512MB of RAM — but it does have a relatively clean version of Android 2.3, access to over 15,000 free Android apps through a third-party app store, and a decent selection of Kobo’s books. So, does the Vox come out of nowhere, weave through the competition, and lead the cheap Android e-reader / tablet race? Or is it simply stuck on Amazon and B&N’s tails? The review below has the answers.
