Acer just announced the Aspire AS5738PG, their first multi-touch notebook, that will ship with Windows 7 on October 22nd. Unlike many mobile PCs that sport a touchscreen the Aspire AS5738PG doesn't fold flat like a tablet, opting for a conventional laptop configuration. This doesn't take away from the ability to use the touchscreen; it just changes the focus of touch technology from that of a tablet.
Rob Bushway's put together a video demo of several multi-touch applications that will be part of Windows 7 Touch Pack. Some of the applications were first seen on the Microsoft Surface, an expensive table-sized computer.
