With every passing year, Amazon finds ways to upgrade its Kindle e-readers and Fire tablets while also lowering the cost of entry. The company’s Fire HD 6, launched last October, broke the sub-$100 barrier, and yet it now looks relatively expensive in comparison with the new entry-level Fire. At $50, it’s pretty much the cheapest tablet money can buy, but don’t let that price fool you. Compromises have been made in the race to the bottom, of course, but the pessimistic idiom “you get what you pay for” doesn’t really apply here. The new Fire might only be the cost of a night out, but what you’re getting in return is a perfectly capable device that sets a benchmark for budget slates.Slideshow-328275
