Android already beat iOS worldwide last year. 70% globally (smartphones).
Android not being "as good as" is a nonsense statement. The product started after iOS and overtook iOS completely. While price is a big factor worldwide, that doesn't explain why in America--where people tend to have more money than smarts and where brand name/appearances matter a lot--Android has taken the lead again. (Do you even have an Android? I have both. Android is better because it allows more freedom.)
Windows is losing the battle either way, though. I just hope Microsoft continues to support the Surface after the product line dies out.
It doesn't surprise me a whole lot. I've got an 4S phone and really envy the rest of my families Galaxies. Although when the iPhone came out it was innovated it now seems clunky and neat obsolete. The iPad is just an oversized iPhone. The look and feel of the Android powered units is just more appealing to me.
Some time in the near future I expect Android to implode on itself. Why you ask? Too many variations, no updates unless you buy a new device and more security holes than a mountain of Swiss cheese. Why little or no enterprise adoption? IT experts know the issues and don't need to take on the load of headaches that come with Android. It may not come next month or next year but its going to happen, just sit back and watch.
IOS isn't perfect but it is safer and has the blessings of enterprise adopters.
