windows 7 sensor and location platform overview

about 6 months ago i attended a session about the sensor and location platform plans for windows 7 in redmond and now information has made it to channel9 here.  although a programming topic, it shows some of the thought that has gone into the new operating system taking into account what current computers (especially laptops) can do.  i'm also looking forward to attending bill veghte's keynote at tech ed 2009 virtually (and bill gates on the today show - it's turning out to be a pretty full monday morning).
