Not as exciting as the iPhone 3G announcement today, but possibly a great update to the often criticized .mac service, is the news of Apple's new MobileMe service. I am not sure about the name, as it kind of reminds me of Windows ME, however the Apple Marketing Department has a little more experience with this sort of thing than I do.
It looks as though .mac has been totally reworked to create an experience for the consumer user which rivals Microsoft's Exchange Server, or what most companies run their email, calendaring and contact lists from.
From the Apple site
You might have a Mac at home, a PC at work, and an iPhone or iPod touch. The challenge is keeping multiple devices always in sync. Enterprises can use a server like Exchange. For everyone else, now there's MobileMe.
MobileMe works with the applications you know well. Microsoft Outlook on a PC. Mail, Address Book, and iCal on a Mac. And Mail, Contacts, and Calendar on your iPhone or iPod touch.
Access and manage your email, contacts, calendar, photos, and files at me.com. All with amazing applications that are so feature-rich and easy to use, you may end up preferring them to your regular desktop applications.
Pricing in Canada looks to be set at $109 per year for an individual account with 20GB of storage, with a family account available for $159 for 40GB of storage for up to 4 users.
Kind of surprisingly it will support Windows PCs and applications like Outlook in addition to those on the mac, but when combined with the iPhone or an iPhone touch the power of this product really starts to shine.
I have never tried .mac for longer than the free 60 day trial as at the time, it really was just an email address (this is going back to 2000), and haven't been too excited about the features it offered, but it might be kinda fun to try out for a year...
I see this likely being sold as an upsell with your iPhone.
