MobileMe

Apple's MobileMe ($99-$149) is a new subscription-based web service that replaces the feeble .Mac service. Redesigned as "Exchange for the rest of us," MobileMe delivers push email, push contacts and push calendars to your iPhone, iPod touch, Mac, or PC, keeping everything absolutely in sync and up to date. Also included with MobileMe is a suite of slick web apps that work and look just like desktop applications. Mail, Contacts, Calendar, Gallery (photos), and iDisk (sharing files) are all included. It may sound a bit confusing in its description, but it'll make your life easier without question. MobileMe will be released alongside the new iPhone 3G on July 11th.
