OK, here's my two cents ... From a design standpoint, it is a LOT cleaner on the eyes. Having all of those categories and links on the home page of the store in its previous incarnation was a real eyesore. So as far as the layout goes, it's a vast improvement. BUT ... the common practice is to design the entire new site on a separate server, and do it so that all you have to do is "flip the switch" and have a big surprise for your visitors the next day. That makes the changes as seamless as possible. But it also runs into problems because you aren't really able to test it completely until it goes live. As others have said, give 'em time to work out the bugs. It sure is a lot easier on the eyes this way!
