I just login to Yahoo Mail, there is a brand new interface. The skin is changed as well! Very fresh!

The most noticable change is the new Application bar.

That sounds somethings like Facebook.
They are added:
- Big Sender - Sending the file up to 100MB and powered by ZumoDrive
- Calendar
- Edit Photo - Online Photo Edit by picnik
- My photo - Online Photo Album by Xoopit
- Notepad
- Paypal - for sending money online

Note that, most of applications are from third parties, not Yahoo themselves. I guess they are really going away from as Application Provider.
