Yahoo Mail upgrade

I had been a long time supporter of Yahoo Mail.
But admit it, they've been sitting on their laurels for too long and lost their standing.
Where Google Mail had multiple selection, I had to select my spam mails in Yahoo Mail, one by one.
Where Google Mail allows you to drag and define your calendar appointments, I had to fiddle with the start and end time in Yahoo Mail.

Now, they have a massive upgrade, with link up to Facebook and Google+.
Question is, is it too little, too late?
