Unless you're Android, which has significantly less apps than iOS and is getting bad press for its malware problems. Additionally, iOS runs on the iPad, so iPhone developers can universally target the #1 tablet in the world.
Google makes very little off of Android. They've been following Apple's lead design-wise (look at images of what Android was going to look like before the iPhone came out). As a free operating system that carriers can exert full control over, it's no surprise that it's #1 in marketshare compared to a single phone on two carriers, but if that doesn't actually translate into profits for Google, developers for the platform, or innovation for the industry, does it really matter? The iPhone is still directing the smartphone industry and getting the positive press, and the iPad practically has no competitors to this day.
