There is a new iphone OS has been launched and it gives really ground breaking performance and this is the only reason I have upgraded my iphone. Though now I am not able to play the free games.
It all really depends on the phone, and the developer support behind it. There are some phones (like another user suggested, check Xda) that are dual booting with Windows Phone 7 or Android on it.
And although not a phone, my HP Touchpad (before it fell out of my backpack while On my motorcycle) dual booted between HP/Palm's WebOS and Android
[FONT=&]Tell me about it. If I’ve known that some time ago maybe my phone would still be functioning properly. Flash can really be trouble for phones. I have good expectations on windows os appolo.[/FONT]
Generally it depend on phone, I will still recommend you to go for android. I mean it is kind of smart, simple to use and one can handle their stuffs easily. The cool thing about it is that it supports a lot of apps and that what makes it differ from other.
