Naturally, I installed the software update... only to wind up seeing nice messages like this one:
I also found that I can't access my iDisk right now (thankfully I haven't really been using it lately so I didn't need anything I had put there).
I realize Apple has a rather gigantic task ahead of it in getting the software out to all of its .Mac users before it does the cut-over to MobileMe. I realize also that they want to do a "big launch" of all this stuff. Still, as a user out here working with the tools... it would be awfully nice if they were set to go when the software update was downloaded and installed.
I guess for now we will need to heed the note: "Please try again later."
