Sure, we knew about the upcoming .Mac webmail refresh, but that's because we're nerds for Apple news (yes, you too - don't deny it. You're reading TUAW, after all). To my surprise this morning, I had an email from .Mac, advertising the new webmail and promoting all the new features. While there isn't anything new in the email, I think the significance here is that they're telling their .Mac customers - who aren't typically the cutting edge, AJAX-slinging type - about this fancy upcoming webmail UI change. This could likely mean that it truly is 'coming soon' (as in, not the Microsoft Vista 'coming soon' kind of way), as they would probably need to give their customers at least some kind of a heads up that their webmail is about to facelift its way into looking almost exactly like their desktop email.
