UMPCPortal comes back to the Clevo TN70M, a Tablet netbook that can last for about 7 hours with its 37wh battery. It is too small for many productivity uses and that includes blogging (for us) and desktop-like web browsing for (most people). Right now, the Asus Eee T91 seems more attractive, but we’d like to see some independent battery life tests. There’s a video here. It looks better than the ones offered by Kohjinsha (cuteness sells) and the main weakness that we found is the 800×480 display.
