To give a perspective from Chicago: About a month ago my girlfriend told me how she was late for work on morning and wouldn't make it on time if she took her usual public transportation route, so she took Uber. I was surprised because I never talked to her about Uber and I usually introduce her to things like this. Turns out its fairly popular at her school and other downtown Chicago campuses. Students just like it better then cabs and find it easier to get a good rate and nearly any time in the day. I still have yet to use it myself, but I feel they are making huge in roads to being a common place name and that alone seems to justify this valuation. This isn't theoretical growth. They are getting huge, and its not just in the tech bubble.
