I have mentioned about MobileMe service launched in Twitter feed during WWDC08 keynote. MobileMe is a new service works like Exchange, and it is similar to .Mac. MobileMe is more powerful than .Mac, since it can sync contacts, emails and calendar with any supported devices. You can also browse photos and files whenever you want. It makes desktop everywhere.

It also uses “Push” technology, so keeping all devices in sync is easy.

For instance, if you have computer at work with Outlook, by using the MobileMe service, all stuff will be synced with server. So, iPhone or iPod touch can get the synced information quickly. And when you back home, the information will also be synced with home computer by MobileMe. No more complex setting using Microsoft Exchange.

MobileMe will completely replace .Mac service. Existing .Mac user can choose upgrade to MobileMe or not. MobileMe service costs US$99 for individual with 20GB storage for mail and storage. This plan will have 200GB monthly data transfer limit. Family account also available.
