Enso introduced the zenPad, an Android-based tablet that starts at $155. The device features a 5" display with 800 x 480 pixel resolution and is powered by a 667MHz Samsung 6410 processor. WiFi is built-in, but GPS and an external 3G adapter will cost you $25 each.
It's the zenPad from Enso, a five-inch, 800 x 480 Android 1.6 tablet with 8GB of storage (on a replaceable microSD) that, for an additional $25, comes with GPS. It's powered by a 667MHz Samsung 6410 processor, pledges six hours of battery life, and has WiFi built-in while an external 3G adapter is just another $35. That means a fully max'd out unit with GPS and 3G would set you back $210 -- plus $25 for shipping.
