It seems weird that Samsung are interested. They're making great devices, but splitting their product line between two OSs just doesn't make much sense to me. It sounds like they're taking a leaf out of Nokia's book in chopping and changing and trying different strategies, and look how their lead in the smartphone market has been whittled away.
Sometimes it's better to make ANY decision, decisively; rather than hedge your bets and see what happens.
Whatever one might say about Apple, you can't deny they have a clear, decisive road-plan for iOS and their devices.
Thats unfortunately typical for many companies these day ... they are not spending the time and money to research the market and do user studies to see what is the 'best' fit - seems to be cheaper to throw a big variety of devices on the market and wait which one survives - customers do the testing for them
