I just noticed a little bug, too -- the new UI determines Today's date using your local computer's clock and ignores the Time Zone setting for your account. Right now, my account says Today is April 22 if I use the new UI, but it says Today is April 21 if I use the old UI.
There was an error with your operation. If you were trying to make a change, it may not have saved. Please refresh this page to try again. Please sign in to AdWords again. If the error continues, log out of your AdWords account, then log in again and return to this page.
This error is BRUTAL. I've been through the process 4x of entering ad copy, keywords, CPCs, etc. after refreshing my browser once, signing out once, and trying in a different browser.
What to do?
What to do?
I loved the ability to check/update little things from my iphone, no matter where I was. What am I supposed to do now when I am on the road? Killing the old interface and not providing an alternative solution for a hand held device is just unprofessional and bad for business.
Please get something going for the iphone!
The new UI is terribly frustrating. Is there any way to go back to the old one?
Sorry to hear that it is frustrating - and here's hoping that it'll seem like second nature before too long.
netmeg is correct that it is no longer possible to go back to the previous interface - so below are a couple of resources to help you come up-to-speed with the new interface:

The Max CPC cells in the new rows were highlighted as the problem. I'm using CA$ and the bid values are shown as "CA$1.00" (left aligned). If I edit those cells to replace the bids with "1", it reformats them to "CA$1.00" (right aligned) and then I can save without an error.
This is an annoying bug.
