Unless you are engaged in the multinational legal goings on concerning smartphone patents you'd have to be delusional to think that this announcement has anything to do with you personally.
If you're a startup, and you're planning to grow bigger in any areas of software/hardware/services that google covers (which, to be fair, these days is a very large range of areas), its definitely something to be thinking about.
Google is becoming an entrenched company, they will eventually (or sooner) go from an innovative market position to a defensive one, and thats when patents start to look really juicy to the bean counters.
Also, if you're a developer working for a large google competitor, you may also have reason to fear at least for your job (which is quite personal).
