It's not just the keyboard. It's all the hardware. It's the keyboard, the various buttons, the speaker grilles, the indicator light, the camera... everything on the Macbook Pro is gorgeous, and it works all sleeklike.
The way this thread is playing out about hardware is the way this page/this situation/this argument is playing out with OS-X/Linux.
"Just use modwifi 0.9.4.1 I don't see why it's a problem you can find it with Google in a few seconds"
"It's not just the wifi, it's all the software. The audio stack, the BSD underpinnings, the coherent feel over many apps. I'd gladly pay more for things to just work, but it's not even that, things just work /nicely/."
The frustrating thing is that both viewpoints are valid, and there're people on both sides that don't seem to get that, and they're the only reason that people are getting into these arguments to begin with.
