It's relevant because every single major (i.e. popular) iOS app has a tablet optimized version that blows the phone interface away. Apps work better, function better, are easier to use, and have more features than their "phone" counterparts.
Twitter?
Facebook?
ESPN?
Major news apps (ABC, CBS, PBS, etc..)?
Major shopping apps (Amazon, Ebay, etc..)?
Yes, preloaded apps - the ones that use Google's own services and are developed by Google - work well and have better Google services integraton with Google-developed OS. That's to be expected. It's like praising iOS simply because it has better iTunes and iCloud integration. The point is that
3rd party apps are lacking.
Is that right? So that's what you'd call "optimized"?

And why would Apple have to "match" the few extra pixels of the Nexus 10? Simply to have the same spec on paper? The 2048x1536 iPad display is a beast in its own right. It looks stunning and the 3:4 aspect ratio gives more vertical space which is often essential for tablet interface (think on screen keyboard).
