You probably don't know Acer for its smartphones, but the company has nonetheless been pushing out handsets for years. Its latest is the Liquid Jade Primo, a Windows Phone teased a few months back, which arrives with a couple of tricks up its sleeve. Internally, it's virtually identical to Microsoft's own Lumia 950 and 950 XL, with a 5.5-inch 1080p AMOLED display, Snapdragon 808 processor, 3GB of RAM, 32GB of internal storage, 21-megapixel rear and 8-megapixel front-facing camera. So far, so Windows Phone. Like the Lumias, it can connect to a monitor and turn into a "PC." But Acer's announcing a second product today that makes that transition much smoother.
