The "Swiss Army knife of electronics." That's the best way Sprint can define the LivePro, a touchscreen projector/Android hotspot made by Chinese manufacturer ZTE. The device, which goes for $300 with a two-year contract, is the first in a brand-new hybrid category -- and depending on how successful it is, it may well be the last. Although the LivePro has a wide range of capabilities that make it useful on many different fronts, its demand will be incredibly niche. What kind of person needs such a unique device, and is it good enough to even attract them?
