MSFTs new mobile OS is truly excellent, but nobody is buying it (except me). Meanwhile Nokia has the worlds biggest smartphone market share, but are close to 0% in the US and falling fast. This is a big bet for both companies.
Even more interesting to me was the announcement of the new HP Web OS devices, the touchbook and Veer. More info here: http://www.digitaltrends.com/mobile/hp-unveils-webos-hp-veer-palm-pre-3-and-hp-touchpad/
