I've been using the new beta interface for the past week.
It has it's positives and negatives for sure. The one thing that has held me back is that it is piss *** slow.

Today I needed to jump in and make a few quick changes, for whatever reason I didnt fire up AE and logged in instead.
The wait between each screenload and for data to appear is painful. Same issue that Yahoo has.

Anyhow, I jumped back to the old interface and felt a warm sense of calm. made the quick changes in a few graceful strokes and clicks... ahhhh. Now I think I'm pretty much decided, I will likely never use the web interface once it has been changed and opt for AE as my primary tool.

Whats your take thus far?
