Big-endian vs. little-endian machines

I understand what the difference between the two are. Looking at the entry in Wikipedia it seems like litte-endian format is gaining ground and this is not as much of an issue as it used to be.

HP-UX on It开发者_开发知识库anium is the only newer processor that is using big-endian format. Most others are using little-endian, which is an indication that industry is standardizing on this. Is this true? Am I missing something? Do any of these differences exist for mobile OS like iOS and Android?

The ARM architecture runs both little & big endianess, but the Android, iOS 6, and Windows Phone platforms run little endian. 95% of modern desktop computers are little-endian.
