The Unisys deal does seem to point to something, though coupled with North Carolina,
what exactly is a little hard to say. My gut tells me they're unrelated: North Carolina is for the cloud (iTunes & MobileMe), and not a test bed for some Xserve replacement:

The Unisys deal (and hints of Oracle courting) points to something similar to the XRAID -- a third-party providing hardware to run the software on.
At the very
least, it's fair to say the news is a public relations ----up, at least for us.
I agree with other posters about the Xserve's service as a gateway drug: For every Windoze box I've retired and replaced with an iMac or Mini on the client-side, an end-user has purchased an iMac, iPhone, or iPod Touch for the home. Every one.
It's because of this that I feel Steve, to paraphrase what he's said himself, truly
doesn't understand the enterprise market. Yes, the people who make the decision about the server don't use it; the other people, who get to see how great the server makes their job, end up voting in droves.
Well, I'll still get a few years out of my current box.
And we'll find out soon one way or the other.
