Everyone says that but cell towers have emergency generators so it really doesn't matter. Of course, living in an area where they actually bury the power lines helps a lot.Personally, I like having my phone service going to a direct phone provider like AT&T so if power goes out and there is an emergency, I can still dial out.
I think MagicJack is Windows only, and requires an existing Internet connection.
