As to 1: it is in many ways insecure (though bound to be hacked might be a bit much.) While dropbox isn't technically a cloud based backup, it can be used that way and there was a period where a glitch left it totally exposed for about four hours ( http://en.wikipedia.org/wiki/Dropbox_(service)#Reception http://en.wikipedia.org/wiki/Dropbox_(service)#Reception ). I actually love cloud based backup, but I encrypt my files before I send them and I am dealing with just my own personal data. A company with data they must legally protect would need to be wary. As to 3: Personally, I love gmail. But from a corporate perspective, you can still exert more control over exchange. This can be significant, especially for highly regulated businesses that need to worry about frequent e-discovery and may perhaps wish to take steps to limit what is sent.

There's a nugget of truth in their concerns which makes them harder to dismiss. Equally, can you say that local storage is more secure, tapes in a "fire-proof" safe, etc? I have reservations about the cloud (Amazon's outage was a wake-up moment for me) but nothing's perfect. As for Google Mail vs Exchange, my personal opinion is that Gmail is superior in evey way. If you need discovery, you can always shove email through your own gateway (running Postfix) and set it to store all emails it sends and receives. You could also use Postini which I think gives extra facilities like discovery. Might be a bit hacky for some organisations I suppose but I've never found Exchange that elegant or easy to manage.
