As long as it's something you can disable (and maybe better yet something that is disabled by default), then I see no issue. For some, I'm sure it could be a useful feature. But yeah, as others have said, my SMS messages tend to be personal while my Exchange emails are work. Just as I wouldn't want my personal email (via IMAP accounts like GMail and Yahoo!) to be synced along with my work email to an Exchange server somewhere, I also wouldn't want my personal SMS to be synced.

Now if there were some way to distinguish between personal and work SMS (other than having 2 mobile phone #s), then I would be fine with synching work SMS to the Exchange server.
