Steve Ballmer has plenty of prior art that could be used to invalidate your patent.
I agree with you - the patent system is broken, and that's the real problem here. A problem, though, is that lots of people see this as a black-or-white issue when I think there needs to be shades of gray. Most people who complain loudly about the patent system just seem interested in having it abolished completely. I think patents serve an important purpose; it's just that the current system/laws rewards people who want to abuse it.
Ultimately a patents strength is defined by how it holds up in court. Getting away with patenting something is only good if it can stand up in court. We'll just have to see what happens (years from now...).
