All that iOS traffic is from Apple users searching for a new Android device while doing a bunch of research to make sure they don't get ripped off again.
Or it could be excessive re-searches due to the ever lovable Apple spelling corrector.
But on a serious note, the market is flooded with a ton of questionable Andriod hardware. I love my S4 and my cheap Memo tablet, but my niece got a cheap tablet for Christmas and it drives me crazy trying to use that thing. Android, like Windows, is not controlled by a single hardware entity like Apple products are, thus the product quality varies from manufacturers. I still wont buy anything Apple as I don't like the company as a whole and I know how to research for quality products before I buy. But for those people that go after the cheapest deal they can get, well, you get what you pay for.
