1. A personal virtual assistant: I first envisioned this as a sort of internet butler, through whom you can perform a vast majority of your interactive browsing, such as facebook/twitter updates, email lookups, movie recommendations and stuff. however, I initially dismissed this as a halfbaked idea. Recently, I read a few articles on Siri[http://www.siri.com/] and I figured that something like Siri would be a better way to go about stuff. The most appealing thing about this idea is that I can easily monetize it by charging a yearly subscription fee.
