For those who don't need a 4G LTE connection on their mobile projectors, the WiFi-only ZTE SPro is now available as a follow-up to the $450 (£305, AU$590) Sprint LivePro. Like the LivePro, the ZTE SPro is a compact all-in-one pico projector. At $400 (£270, AU$530), the LivePro ships with Google's Android operating system, a capacitive touchscreen to control the projector, speakers, and a built-in battery.
