I actually lean the other way - if I'm stuck with a crappy modern laptop keyboard on my mac book I find I'd rather use the same on the desktop - least that way when I swap from one to the other I don't need to adjust to radically different key travels and feel.
That said I can def see where you're coming from - perhaps a nice full travel extended wireless keyboard for those that want decent keys like the keyboards of old, with the macbook style one for those of us who want consistency between desktop and portable (even if that's just consistently sucky lol).
Course with the retina macbook having a redesigned keyboard all of its own, they'd need a different desktop equivalent for that too 🙁
A "full travel extended keyboard"? At that rate (full travel), in order to get around all the hassles of differentiating between Bluetooth and USB dongles, you might just as well simulate the wireless connection with a cable! The idea here is *small*, *sleek*, and seksi. Independent. Free.
Seriously, though, although the world was not in fact flat in the 1500s, it's turning that way now. ;p
I hate using the work-authorized ("imposed") Dell Precision M4600 away from my desk. At the desk, fine, lock and dock it with the blade connector and use the keyboard that is in my ergonomic workspace. The "windows" mouse is somewhat ergonomically attached (there could be improvements.), and I admit that I grew to like the left-click, right-click, and scroll wheel solution, in spite of my desire to remain a one-button purist. I wish my hand-carry mouse were Bluetooth, though, and I wish the Plantronics speaker-hub would "dock" for communication over the "charging wire" - or even run on Bluetooth. The M4600 is like 1.5" thick from a flat table, so your hands are practically up by your ears, and the keyboard feels terribly inaccurate. It's clear that these WinDell ecosystem parts were not made to play well together! (The best news in all of this is that I get a new laptop in a couple weeks (still not a Mac >|, but newer). I think I'll lose like two pounds in the process.)
I get the benefit of full travel and weighting in, say, a piano keyboard, but in a data entry keyboard, no way.
