I depend on Google Voice--so much in fact that my next phone will probably be Android since it handles it natively. Being able to reply to SMS messages from within your browser (or even better, Chrome extension) is just so nice and convenient and solves a major pain point of mine. Also, it's very useful for blocking calls (ladies, where you at?) or for fun, have customized voicemail greetings to specific groups of people or to your girlfriend.
