I've heard the "fit and finish" argument frequently, both in print and in person as the owner of an HTC Incredible. I don't really see it myself, though. Sure there are a lot of junky looking 3rd party apps, but this is true of iPhone as well. Unlike early Windows vs Mac, I don't have this reaction to the base system. What are people reacting to when they say this? Or is it just a canned response?
Even something as basic as on-screen typography is much worse under Android.
Is it visibly different within apps or only when dealing with the system? For example, he concludes in the article that the Yelp app is pretty much identical on both systems. Do you disagree? I'm sensitive to kerning issues too, but I'm not sure the iPhone is in the lead here.
