Runs Office, interfaces *correctly* with Exchange... Enterprises will love this thing
No more "oops, keynote changed the formatting"
And calendaring will work like it's supposed instead of being treated to 2nd class citizens like the whole iOS world has to integrate now (delegate handling is atrocious)...
CxO's everywhere are already hearing about cost of operation of two end-user platforms, Apple versus Microsoft... Not enterprise secure versus uh... "experienced"...
In the end, competition will be good for us, but Apple may not understand how to compete when it has 95% market share, where as MSFT does, and even knows the mistakes it made when it did...
There's just SO MUCH that MSFT can tie an information appliance such as a tablet to, all the backend plumbing, databases, SharePoint, Azure that the iOS world doesn't "get"...
Even if these devices were inferior in terms of hardware, the total value proposition from a CxO point of view is actually really good. iPads encroached onto the enterprise market because end users demanded access from their own devices. There was no "sanctioned" alternative, now that there is, is Joe Normal still going to go buy an iPad if work supplies him a Surface??? Dunno...
The big question is, will the Surface be as disruptive to the iPad market as say, the iPhone was to RIM?
NEVER underestimate the MSFT guys - they're a lot more talented than most think or know, and... They've definitely learned from "think different".
