I have neither a CS degree or a Masters, but I would say if it's only a year, go for it. The world is really competitive for newly minted CS graduates, although probably less so for UPenn, but the masters still puts you at the head of the line. Even in the entrepreneurial world it may still help in fund raising. Grad school is a good place to look for like minded founders.
