Re: Um, no.
"The problem that Android has is the concept that one size suits all."
False - Android also has a concept of sizes, and developers have the same ability to provide different resolution bitmaps. IIRC the sizes are categorised into 4 sizes, which matches the 4 sizes you claim for IOS.
Not that providing just one bitmap is a problem, as any decent API can happily scale it for you - this is 2013, not 1990.
I know that Apple's platform unfairly gets more attention and support from companies, despite fewer users - I do wish this would change. I suppose we should be glad it's not as bad as the lack of support for Symbian (number 1 platform until 2011). But still the question remains - whilst people might write two versions of a UI, where's the support for the new 8" device? And as you note yourself, apps don't support the iphone 5's size, and have to be recoded. Meanwhile, new Android sizes Just Work, and an Android phone at 5" isn't that different from a 7" device anyway.
I would also question your numbers - my apps haven't been rewritten for larger sizes, but they don't need to be - are they counted in your numbers, or not? In many cases, a well designed UI can scale to different sizes. Please don't tell me IOS requires UIs to be designed in something absolute like pixels, that would be stupid.
A 10" tablet is still an oversized phone - an ultra-portable laptop with a real OS is always going to give a better optimised UI for the space, anyway.
