If I already own FSX should I buy the Steam Edition?

That decision is up to you. Your existing boxed version of FSX will continue to work after the release of FSX: Steam, however future updates will only support the Steam Edition of the simulator. We have made some functional changes to FSX in the development of FSX: Steam Edition most notably replacing the now-defunct Gamespy multiplayer systems and enabling multiplayer to work seamlessly once again over Steam.  However, in terms of content nothing new has been added at this time.

Please note that non- Steam distributed FSX addons may not work with FSX: Steam Edition and if you have any issues with them you should contact the developers themselves to troubleshoot the problem.
