There appears to be a new netbook maker on the block. Always Innovating has announced a new touchscreen netbook that purports to offer users four devices in one. The new Touch Book from the Menlo Park, Calif.-based startup weighs in at less than two pounds with an 8.9-inch screen and has a battery life roughly three times longer than most netbooks, according to the company. The device features a tablet screen with a 3-D touchscreen interface as well as an optional detachable keyboard. It comes preloaded with a customized Linux operating system.
