Don't be so baffled.
Think about it.
Those errors will most likely be fixed. It's Apple.
Do I think they will be fixed? Of course. But you are sitting here boasting that Apple's maps are better. Well, right now, they are decidedly not. To put it more simply, you are boasting over something that might could be, but isn't yet. THAT, sir, is what baffles me. Because Google Maps most certainly did not get "clapped" as you put it. Not by what we have seen so far in real world use, anyway.
There is also something to be said for Apple's failure thus far to fix Siri, Photostream syncing, iMessages send/receive errors, and probably a few other things. Remember, this is Apple, not God. There is a huge difference.

Transit directions will be there, just not provided natively by Apple. Third party will be able to tie this into the Maps app from what I'm reading.
So third parties will have direct access to the maps app? Or will we need to install a transit app that we launch that then in turn launches the maps app and gives us these transit directions? The first I can certainly live with. The latter is pretty inelegant.
Also, where did you read this? I woud be interested to have a read myself (not because I don't believe you, but because I am generally interested).
