I'm accustomed to the new interface now. I started using it the day it was launched, so I don't have any problems with it.
I like the old one much better. I was so used to it and I knew where everything was. It is hard to find where things are with the new layout.
The drill-down is really handy. The only thing I miss from the old version is the map with the pin-points, and I think all in all it's a good deal. Especially for free.
