I don't know why people don't like Steve Ballmer, I think the guy is entertaining during presentations and has brought Windows a long way since the Vista flop. We now have Windows Phone, Windows 8 and Xbox set to perform increasingly well and integration has finally come around. One thing we have known for a while (since Microsoft announced they would introduce Metro UI to the Xbox and Windows 8) is that the Windows Phone platform should gain some momentum through a unified experience.
As Ballmer replied to a post-PC era question at a recent company shareholders' meeting:
"We've got broad Windows initiatives driving Windows down to the phone. With Windows 8, you'll see incredible new form factors powered by Windows from tablets, small, large, pens, smaller, bigger, room-sized displays."
The reception of the new look of not only Windows 8, but the upcoming Xbox dashboard refresh too, has been generally positive. Sure there is some skepticism as there would be with any radical alteration, but the combined eco-system will eventually prove to be the best chance for Windows Phone to pick up some speed. Metro UI will be the backbone of the Windows interface and will differentiate Microsoft's product line from competitors.
