You ever try Nokia Maps? They were truly ahead of the game with it but since no one was using Win Phones, it couldnt catch on, and Nokia phones were dying around that time but it was a great navi system.
Google Maps is the true monopoly that the regulators should go after. GMaps is the new Yellow Pages, at least for me. If it's not on Maps, I'm not going to find it.
The big problem with Windows Phone was that the Metro UI design was so strong and distinct that devs had to conform their apps to it. Like, imagine if Instagram had a Windows Phone app. It wouldn't look like Instagram. And those companies invested gazillions into their app designs and didn't want to redesign it for a niche device.
it really wasn't a big deal because so few people had the original iPhone with 1.0. It was only available through AT&T and was very expensive. And iPhone 2.0 came out before Android 1.0.
