Acer plans to offer three tablet options with two supporting Google's Android OS and one running Microsoft's Windows 7. The difference among the Android based options is primarily size: one will be a 7 inch version and the other 10.1-inches.
Both of the Android models offer HDMI support and wireless connectivity through Wi-Fi and 3G. Expect them to be available in April of next year.
The Windows 7 version will be offered as a 10.1 model only. It features both front- and rear facing 1.3MP cameras, and a docking station that includes a full-size physical keyboard. This model will be 15mm, slightly thicker than the 10.1-inch Android version. It will also have support for both Wi-Fi and 3G connections. It will be available in February of 2011, sooner than the Android models.
