Perhaps this is one reason why WP7 has had such a poor uptake. Are most handset manufacturers "running scared" of the Microsoft blight?
You don't consider HTC and Samsung major manufacturers? They had Windows Phone 7 models at launch.
I think HTC's approach is great, make good hardware then make models with different OS'es
Remember WP7 has only been out for less than 1 year.
Looks at the Android version history, it's not till recently Eclair and Froyo onwards that Android started selling significant numbers.
