Acer may be planning a dual-screen model reportedly leaked prototype would have two 15-inch displays, both of which would be touchscreens; one or the other could replace the physical traditional keyboard and trackpad with touch input for both. Either would support multi-touch and could switch to drawing gestures for special tasks.
The laptop has an Intel Core i5 CPU (2.67GHz) and runs Microsoft Windows 7 with a 15&Prime display. No release date is yet known, but our source says Acer is aiming for fall 2011 if the device makes it out of development. Our source says the unit is "still slow and buggy", so it's definitely still in its early stages of development. Both displays are multitouch enabled and the laptop allows you to "swap" screens if you choose.
