The Surface concept was great. It was a Windows PC inside a table with a 30" touchscreen on top, and cameras that could sense what's happening on screen. The result is you could use a Surface device just by touching the screen with your finger -- but unlike other large touch screens at the time, Surface was multitouch, so you could use all your fingers at the same time. More importantly, multiple users could engage with each other. It was a PC but didn't look or run like a PC, which was genius -- you'd never know it was running Windows, but there was no development learning curve. It was totally optimized for that big honking touch surface area, and applications that worked with it -- I'm sure it could run Office, but that's not something it's was ever likely to do. Surface was PC evolution happening in real time. It's really something you needed to see up close and in thirty seconds before the light bulb went on. Sadly, most people have never seen or worked with a Surface unit. Beyond a small retail rollout at AT&T stores in NY that seems to have ended, the last time I saw one was the Edelman PR offices, where it sat like a large coffee table and did pretty much nothing.
