I upgraded just for "Save settings on server", and I ended up with the new account screen to my surprise. It takes some getting used to, I'll admit. I do like that you can customize what fields you want displayed. Like escargot and frogs, it appears to be an "acquired" taste.
With the default font and all fields shown, the new account window is 700 pixels + (however much it takes to show your portfolio) high. I could easily see how it could exceed my 1024-high screen some days.
