I am fairly pleased with MobileMe. It is very useful for me and defiantly worth the $99 a year. I use iCal a lot- well, for almost everything and would have to sync my iPhone many times daily to have the latest events on it. With MobileMe, that is no longer. I have had great luck with push so far and am pleased. I fand the web interface slower than .Mac, but I hardly use it so not a big deal to me.
