I would say that it is notable that the author has apparently never used iOS. Setting all subjective judgments of whether iOS or Android is better to the side, what that means is that the author hasn't even tried out what is by far the largest app/developer base available on a tablet. So I don't really think the author's opinion bears much weight, when we have facts staring us in the face such as the near-universal adoption of iPads in Fortune 500 companies, sales figures clearly showing that many users are buying tablets instead of laptops now and apparently are doing just fine, etc.
If by developer base you mean market share, Android tablets are selling more than iOS nowadays. Apple is 43.6%, Android over 50%. Nowhere near the huge lead Android has in smartphone market share, but still enough that people going for the biggest market should chose Android:

Not really surprising considering competitors like amazon aren't even trying to make a profit on the hardware cost and are selling the things at rock bottom prices. Most business solutions I saw at CES were using Android tablet bases as well now. I guess due to the low price and because you can customize the entire software stack for health care providers or whatever you are targeting.
What? Developer base mean developers, not users. Developers are more with iOS (better dev tools, better monetization, less tech problems, etc) Is well understood. The most quality apps are in iOS. That is a fact. The most qualified devs are in iOS, that is another.
Android have the market share, but the quality is not there yet (as compared with iOS)
