Last week, I posted this tounge-in-cheek suggestion.
Wouldn't it be great if there was a proper show-down between the two major players? You could really compare which OS was best given the same hardware. Is iOS's camera software better than Android's when given the same lens and CCD? Which runs faster when CPU, GPU, and memory are identical?
According to WP-Life, Samsung's Galaxy S III will run both Android and Windows Phone 7!
Judging by the article, there will be some cosmetic changes - but the basic hardware will be the same.
What a show that will be! I think WP7 is a beautiful but flawed OS. Android is powerful, but struggles on anything less than excellent hardware.
One day - one glorious day! - we may see hardware which will accept any software. Imagine, just like a PC, being able to buy the hardware and then choose which OS you want on it. I've written about porting Android to Nokia hardware, and I run Ubuntu on my MacBook Pro.
A true ecosystem involves freedom to move between platforms without artificial restrictions.
