I can type faster and accurately on any keyboard. In fact once you've learned how to touch type, you can type on any kind of keyboard.

But you are missing the whole point.

Apple's flat keyboard is designed to look nice. Glossy finish, easy to carry and use cases around that. This looks like a keyboard designed for people who don't treat the computer as a work machine but as a utility device. More like browsing the internet or for writing emails.

But if someone is going to spend hours doing some deeply involving work like solving a problem, or trouble shooting or laying first bits of a project or stuck in deep with some interesting issue for hours. Which if you take your time seriously, you will work on such tasks anyway. Then comfort becomes a more important factor than looks and cuteness of the tool.

This is where IBM Model M scores over the glossy Apple's keyboard.
