We'll see how many apps actually work well though, and which ones have to be tweaked. Not every developer follows the standards. It's not like Apple even does

We'll see how many apps actually work well though, and which ones have to be tweaked. Not every developer follows the standards. It's not like Apple even does either. The recent iOS 6 apps store on iPhone is a good example of something where they made the tap targets too small to expand app updates and it was very frustrating. They finally fixed that just recently so that the target was much larger.
