Sure, you probably don't need a smartphone with a massive 4,000mAh battery and a trio of SIM card slots, but thanks to Acer, your author can't stop thinking about one. Acer's so-called Liquid X2 is clearly well-equipped to play globetrotter, but (just likethe Predator tablet) the company's spokespeople were awfully light on the details. Still, we know it comes with a 5.5-inch screen and a 64-bit octa-core processor thrumming away within its surprisingly sleek frame, along with a pair of 13-megapixel cameras nestled high along its face and back. At last, a device that takes selfies as seriously as HTC's Desire Eye.
