Personally I found the keyboard a breath of fresh air when I switched from Windows/Linux. The whole text editing experience is gloriously consistent and logical, though marred by a growing number of cross-platform apps that don't behave correctly.
What I think of as inane is Linux's having a slightly different key combo for copy depending on what context you're in. Or all the mad extended keyboard keys I used to use that were in a different place on every laptop.
[the keyboard experience is much less well thought out on non-English keyboards though, as another comment points out, come on Apple sort it out]
