Don't see a lot of Macs running Oracle, SQL and the grandaddy of them all....Exchange, in the enterprise.

The number one platform that runs these is Win2k3. Except for Oracle where HP-UX is the clear leader.
I will say that Vista is a non-starter in this arena...nobody wants it. Heck, not much XP usage either. But there isn't any appreciable Mac presence.

Not yet.

You are right on, of course, but I think they are pretty much talking desktops here.

It should be noted that what IT professionals say on a questionnaire and what the company will actually approve are often two very different things. I can attest to that first hand.

Oracle 10g is available.

Exchange Server could be hosted on Macs, but I'd rather see Apple deliver something better than Microsoft and RIM's stuff - and position the iPhone as a better platform than the Blackberry for corporations.

I believe that Apple will eventually spin off a unit for enterprise systems - without the Apple logo on the front panel.
