I’m pretty happy I didn’t use MobileMe (since I was already a subscriber of .Mac) to keep my contacts, calendar and email in sync, and rather chose mail2web’s hosted Exchange option. With Exchange, my contacts are synched from Entourage to my iPhone and other Macs instantly, and so does my email, calendar and invitations to events. It has a rock-solid feel that right now MobileMe cannot seem to provide. I’m sure Apple is working hard on their own version of ActiveSync for OS X Server, which I’m also sure will work wonders, but right now, if you want Blackberry-like experience on your iPhone, go for Exchange (hosted or otherwise). The motto should have been “Exchange for some of the rest of us and only sometimes”.
