Microsoft is making a lot of ios apps... I guess they're trying to get apple fans attention and showing them metro.. Just add an apple logo at the back of the surface tablet and name it iFace or iSurf that will help them with sales...
Its a great little APP, and its great that microsoft made an IOS app of smartglass. If the two companies were reversed and there was an Apple console, Apple sure wouldnt make any WP or android apps for it.
