Chromebook fans have a new option for a touchscreen laptop. Meet the Chromebook C720p, the $299, all-white Google-only laptop from Acer. Its touchscreen is a low-res, 1366 x 768 pixels, but the deal sweetens with a USB 3.0 port, HDMI-out jack, full-size SD card reader and an estimated 7.5-hour battery life courtesy of a low-power Intel 4th-generation Core Series CPU. Plus, the only other touchscreen Chromebook is the $1,299 Pixel. That’s one big price gap.
