SE, Samsung, Motorola, HTC are all heavily invested in Android and are miles ahead of Nokia. They can chose to run an outside lane in that race, or they can lead up Windows Phone 7. All people with WP7 devices are just token efforts, Dell, LG aren't major players like the aforementioned companies are, HTC owe everything they have to Android. Nokia can take WP7 and become the market leader, with Microsoft investing heavily and Nokia providing world class hardware they can provide a point of differentiation as opposed to becoming one of the crowd.
