The latest smartphone from Acer, and reportedly a rival to the Google Nexus One superphone, the Acer Stream has now gone all official and we have a video demonstration of the Acer Stream in action for your viewing pleasure below.

The Acer Stream is said to pack Android 2.1 OS along with a “brand new” user interface which has been describes as a “stunningly fluid 3D skin,” reports an article by Kat Hannaford over on Gizmodo.

Spec wise the Acer Stream offers a 1GHz Snapdragon processor, 3.7 inch WVGA AMOLED touch screen, 3G, 5 megapixel camera with 720p HD video recording, Bluetooth, WiFi, 2GB internal storage and bundled 8GB microSD card.

There’s no word on a release date or price, but the device is apparently expected to hit in October as we reported (here). The video comes courtesy of Android Community, although is not in English but does give us a look at the Acer Stream…enjoy
