Much of the time, I'm an Android user myself, so I'm happy when something is available for Google's operating system and sorry when it isn't. But despite the fact that iOS's market share is much smaller than that of Android, and has been for years, Apple devices are still nearly always first in line when a major company or hot startup has to decide where to allocate its development resources.

The tortoise is faster than the hare. Sure, you have to cut off the hare's legs first, but then, sure, yeah, the tortoise is faster.
