Battle of the dirt-cheap tablets: Amazon Fire HD 8 vs. Walmart Onn 8

Apple's iPads get all the headlines, and with good reason: They've long been considered the best tablets for most people. But none of them come cheap. For folks on a tighter budget, I've spent the last few weeks testing a couple of 8-inch slates on the dirt-cheap end of the price spectrum: the 100 (but frequently discounted) Amazon Fire HD 8 and the 79 Walmart Onn 8". They aren't the only tablets available in this price range, but they're pushed directly by the world's two largest retailers, so there's a good chance casual shoppers may buy them without knowing exactly what they're getting. We pitted the two slates head-to-head not only to figure out which one is better, but also to diagnose the state of ultra-budget tablets as a whole. You'll never get truly "premium" hardware when you shop in this price range, but the Onn makes a nicer first impression than Amazon's Fire tab.
