Acer has been showing off a 7-inch tablet PC. The Android based tablet was amongst a pile of other gizmos  such as e-book readers, all-in-one PCs and smartphones in Beijing.

The tablet PC uses a processor from Qualcomm is expected to hit the market in the fourth quarter of 2010. Acer's tablet has a full QWERTY keyboard at the bottom which reminded us of the Kindle e-reader.

Acer CEO Gianfranco Lanci, presented the device without much comment at the company's press event and refused to comment on hardware specs. The display was confirmed to be a 7-inch color touchscreen, which is the main feature that keeps it from being a plain e-reader.

Acer also introduced a multimedia entertainment system, the Acer RevoView, and a home-use storage system, RevoCenter, both are capable of connecting to devices such as PCs, handsets and e-book readers through wireless networks.
