My neighborhood finally got FIOS and I'm think of switching for Internet only. Right now I use DSL via Airport Extreme and Express extended to the network. I've Googled a lot about how to connect the Airport to the Verizon Actiontec router so I'm familar with what has to be done. What I'm curious about is whether there is any downside to going FIOS. I crave the extra speed as right now I have no DSL upgrade path, but once I go FIOS I don't think Verizon will let me go back to DSL.
