Working Microsoft Surface
Happy as we were with our new Surface we forgot the basic rule of Windows related problems; reboot if in trouble.
We spend quite some time calibrating, recalibrating and reading documentation from the invite only Microsoft site without any effect. In the end Vista asked us to install an update and to reboot the Surface. When it was rebooted we ran the ‘Surface Shell’ application from the Desktop and suddenly it worked!!
The Surface, or at least our version, comes with a set of code examples. We tried several to see how well it works and found out that especially the Grand Piano demo is a crowd drawer (mainly due to the sound probably). The Piano is a limited set of piano keys in perspective view. ‘Pressing’ a key results in a tone, just like a real piano
