Q: Why a UPC?
A: The Sony VGN-U50, Sony U70, OQO, Flipstart, Tiqit, and Antelope are Ultraportable
Personal Computers that are meant for a person who wants to run Windows or Linux applications and carry a very portable handheld device (similar to a Pocket PC PDA) running a fully operational version of Windows XP or Linux.
"We wanted an ultra-personal computer that you always carry, but that was still
powerful enough to be your only PC"
