Is Google making a web browser?
Some people are seeing Google in their logs. It says "Google 0.X" listed among the other browsers, not robots, not search queries, but browsers! 0.X is the version number of beta software - software in production. So if you think these logs are mistakes, recognizing the GoogleBot instead, I don't think so. GoogleBot is at least in version 2.1. Still a chance this can be wrong.
