Is Facebook The Future of Email?

I’ve been using Facebook more and more over these past few weeks and I really like the email functionality. Since the service is fully integrated with mobile devices, I can be notified when someone sends me a message on my mobile phone and read it on their mobile interface which works great on my 2 year old RAZR with the crappy embedded browser (Opera Mini doesn’t work reliably for some reason).

So is this the future of email? Perhaps but you still can’t read your Facebook mail on an airplane or anywhere without an internet or mobile connection. I’m sure they will have a solution for this problem at some point…
