ThinkPad USB TrackPoint Keyboard (http://lenovoblogs.com/designmatters/?p=2364)
I would love to use one of those on my laptop computers.

It seems that the Ultranav only comes with Touchpad (which I don't like) and in a non-standard layout.

But do you say implicitly, that there's no manufacturer who produces PC keyboards using the apple switches?
Back to the OP's question.
You might be interested in Logitech's new "Perfect Stroke" scissor switches.Show Image(http://www.logitech.com/repository/1647/jpg/14778.1.0.jpg)

If my 2010 predictions come true you will see a LOT of chiclet Apple Aluminum clones this year.
Big difference between a well designed scissor switch and the IBM PC Jr.
Anyway, these are supposed to have about 3mm of throw so a bit more than a standard laptop. I expect a lot of R&D to go into scissor switches. The chiclet flat-top key part I could do without.
