Yahoo Mail presented me with this
when I logged in today. Not too suprising too, but Yahoo!, once a leader in web applications seems to have ended up playing second fiddle to Google.
I was one of the first to get the 100MB upgrade (in 2003 if I remember right), and then the 1GB upgrade, and the upgrade to the new Beta interface, and looks like my early-preview luck still holds. Came across some reviews too.
