Thanks for the info.
Hmmm... I wonder how many sales we just made for Microsoft.

It's a shame, because the main keyboard is, other other than the top line of keys and palm-wrest, a reasonable compromise between between the current fad for paper-thin keyboards and something usable - along with being more reasonably priced than these other options we are talking about.
I see Matias make the same mistake (for my use) as most others, of dedicating keys to cut, copy and paste - I never use them (my fingers are already programmed for Ctrl+x etc.) - so they are a complete waste for me. I'd say the home/end/page keys could take some getting used to, but that goes for pretty much any keyboard that's not completely standard. That Ctrl key next to the N is a bit odd.
What about this cable between the two halves? It looks a bit flimsy - but unlike the Kinesis it looks like it unplugs, and maybe that will make it less likely to break if something knocks half the keyboard off the desk?
