Even as long as I have worked in the software and technology field, I'm sometimes surprised by the reaction of people to new products. Microsoft Surface elicits the strongest responses of anything I have seen in the last decade.
When people read about it, they wonder why they would want a 250 pound PC, or what could be an iPhone for Paul Bunyon. They ask why public sector customers would be interested at all in this device.
When they see it in person, however, it's a different story. Simply put, Microsoft Surface is irresistible. People of all ages want to touch it and find out what it does. It truly is a different way to interact with a computer.
As for public sector, they key seems to be visualization of information. The Microsoft Single View Platform, weaving together Virtual Earth with business intelligence and line of business systems, is powerful on the Surface. The ability to activitate map layers and show data in new ways is exciting even to a jaded observer of the technology scene.
