I thought I'd hate the Apple keyboard (on my MacBook Pro) but I ended up really liking it a lot. Even more than my nice mechanical keyboard. It's very quiet and I can type much faster than I can with the mechanical keyboard.
As much as I love my Das Keyboard, I must admit I don't mind the Apple keyboards at all for most tasks. If I had to do anything like transcription, then yes, but for most tasks like programming or surfing, I'm surprised how seamlessly I can switch from a mechanical keyboard to an Apple keyboard and back again.
Their macbook keyboards, while similar, have totally different feel. I don't know why, I wish desktop keyboards would be as awesome as laptop ones
