An observation.
There's a bizarre inconsistency in the videos coming out of Microsoft. The video for this (pretty bleeding cool) evening-and-weekend side-project couldn't sell anything, but that's not the point. The Mango video[1] looks and sounds pretty good, like it was made by professionals. But their Windows 8 videos[2][3] are unbelievably slipshod. This is so counterintuitive.
Obviously, the Mango video is intended to give some dearly-needed promotion to a fledgling product in a fiercely competitive market. But Windows is their flagship product! The [3] Win8 video was watched by 10x as many people as the [1] Mango video, so obviously these early Win8 previews are getting a lot of buzz. But the more recent [2] Win8 video shows only subtle, insignificant improvements over the earlier [3] video (the sound is better-recorded).
I would love to know why such little care is given to the public unveiling of a product that's tremendously important to their customers, and their bottom line, while absolute TLC is showered on something that doesn't even have a foothold in the market. They obviously have the tools and talent to do better, so someone decided not to exert the effort. This fascinates me.
