I strongly dislike this direction of Apple's design, seen also in the new MacBooks. You ask, "What is the point of doing away with all of the ports and support electronics if you need an big, ugly, cumbersome adapter to make the device useful again?" and in response hear judgmental sneers that you aren't their target customer anymore, you power user.
But I guess that's par for course for the consumers that clad their fantastically stylish sci-fi pocket supercomputer marvels of manufacturing in neon Croc-rubber.
