Just for trying it out once or twice, sure.

But my world depends on my primary email. I get notifications on my phone from it. I have my calendar, my Picassa, my documents on it and I also use Google Talk quite a lot lately.

And because I did the recent migration, I cannot have a parallel regular Google account tied to this email address; it used to work fine this why with some minor pitfalls.

If you don't have a Google Apps account that you really depend on, you can't feel the same pain I do :)
