Since I have extremely similar goals post MBA, I have looked at a lot of schools in this arena. Here are some more to consider.
Stanford: As mentioned before, Stanford is great for technology start-ups. Extremely hard to get into and the most selective school in the entire nation, but possible the best place for what you want to do.
Carnegie Mellon University - Tepper: I have found few schools that have such a Tech focus. Arguably, CMU caters more to tech folks than MIT. Sloan is somewhat trying to shed the heavy tech label that they have and prove that anyone can go there, but CMU seems to embrace it. They also have several solid Entrepreneurship programs.
Generally speaking, a strong engineering and computer science program were important to me. I feel like one of the best ways to start a Tech company is to partner with a person focused in Tech ... and that happens when there is a good engineering/comp sci school for you to steal talent from. As a result, Unv of Michigan was also on my list, but I can't hands down recommend them.
