It's only the best thing out there! I get to sync my contact, calendar, notes and more with MobileMe. What if you lost your iPhone? Did you know you can log your iPhone remotely from your computer? You can even wipe it clean if you don't want people to get data from your iPhone. How cool is that?
It's also web based so lets say you don't have your phone. Your not near your computer. You can log into another computer and got to www.me.com. Log into your account and view your .mac mail, documents, calendar, contancts and more.
There is so much more this application does that will make your life easy.
