Samsung SUR40 for Microsoft Surface hands-on with video! (update) -- Engadget

Microsoft offered a brief glimpse of its revised Surface earlier this week at the Ballmer keynote, but now we've had a chance to check the Samsung SUR40 for Microsoft Surface (as its officially termed) for ourselves. The "2.0 experience" firmware is early and a bit buggy right now (especially with finger input), but there's plenty of time fix that up before its launch later this year. The hardware itself is much thinner, with a 4-inch profile that can now be placed vertically against the wall (although we suggest using the stylish legs when possible). The 40-inch 1920 x 1080 gorilla glass display was crisp as all out, but since we could get close and scrutinize, you'll definitely notice the pixels. The first demo we got to see is also probably the most impressive, wherein a paper with "I can see" written on it is scanned and read very clearly (a dev monitor was hooked up to show what Surface could "see").
