Ultrabooks are a great step forward for Windows mobile computing in terms of portability, but because of its aluminum form factor it's not exactly wallet-friendly. That might change in the next few months, as it has been reported that cheaper plastic-based Ultrabooks are en route. These upcoming lightweight laptops will be a using a variety of plastic and aluminum materials, with the casing built on a fiberglass-like plastic. Intel has indicated that these alternative materials are just as effective as a metal chassis during torque test demonstrations. According to Intel's Taiwan head Jason Chen, we could be looking at prices ranging from $599 to $699 for these relatively affordable Ultrabooks, which are estimated to arrive at the second half of 2012.
