I'm in the process of upgrading 3 seperate accounts.
My biggest surprise, so far, is the inability to bulk update bids for an adgroup or ad. You have to click into each keyword seperately to see the bid range and make a bid adjustment.
It seems strange that they wouldn't allow you to do it all on one page as you could in the old overture and still can in Google or MSN. I suspect it's a desire to obfuscate bidding in order to increase overall bids. Unfortunately it means I'll shift my budget towards other systems where I feel more able to manage my performance.
