Ya, the post title is a little overstatement. You cannot literally install windows phone 7 OS on your android or iphone device. But you can try the basic features of it on your android or iphone/ipad device. You do not need to install the OS. You do not need to even install an app. Microsoft came up with a browser based simulator of their new OS. Just click this link in your phone to get a feel of it.
I liked the idea a lot. Its amazing. What else is a better way to give a taste of new OS to users using a different OS. I think this idea will bring down the resistence level of users to try a new OS. Traditonally approach will need the user have to buy a device to try out the OS. Or alteast try it in a store without actually buying. A different approach with much less resitance level could be to give an app which would simulate the OS. But this browser-based approach has almost no resistence from the user to try the new OS. I agree that the exposure to the functionality will be limited but atleast it gives a taste of it with just a click.
