Although I didn’t write it agree with it. Not that the Windows Phones will replace iOS mind you. It is that Windows Phone is a fresh take one what a cell phone OS should be. Honestly almost all operating systems are pretty much the same now. You have four to seven homescreens that you fill with widgets and apps of varying shapes/sizes. When you want to move from one screen to another you simply “push” that screen to the left or to the right to get to the next one.
Normally there is very little connectivity between these apps, even if they are the exact same subject. For example take all your friends and contacts, Windows Phone makes it ten times easier to find out exactly what is going on with them all levels. All their recent contacts with you, twitter, facebook, even pictures….it is seamless. Check out the video for a demo of what I’m talking about.
This is the type of integration on all levels of Windows Phone, that makes it a “game changer” and “ground breaking” much like iOS was when it came out. I believe that others will soon follow suit. Do I think you will see a bunch of tiled OS come out in the next 5 years? No, but you are already seeing other OS’s trying to get that deep integration in the social area of the phone. Soon you will see variations of the “hub” concept creeping it’s way into all other Operating Systems.
Bottom line here is as time goes on phone will trend more toward the Windows Phone style of seamless interface, and trend away from the “a place for everything and everything in it’s place” style of iOS.
