Apple will be launching the new .Mac webmail system soon. The new interface is looking much like what you’ve seen on OS X Mail application. Apple said the new webmail would have what they call Smart Refreshes, a function that will refresh only part of the page that needs updating; in another word, it’s AJAX!
“The new .Mac webmail is coming soon, and you'll feel like you've seen it before. With its smart use of the latest web technology, it'll remind you of the Mail application on your desktop, with a simple and elegant interface, drag-and-drop capability, built-in Address Book, and more.”
