If you are a user of a product and can't code, if your one developer dies, the project dies. Just becaues it is opensource and everyone can see the source code means nothing. Think about it, what if i opensource software that is so complicated, and poorly coded that no one can maintain it. Just because you smack an OSS lable on it, does not make it quality.

In the end, the answer is, it does not matter, Windows 7 will just work. When I try my annual "lets try linux again" I go to distrowatch and try to pick one of the 300+ flavours of linux to install.
