Quick update;
Got my K840 in and I almost don't believe it's even a mechanical keyboard. These Romer-G switches are so mushy I can't even tell when they've been activated, causing significant slowdowns with my typing, and even increased typos.
I'm not a mech KB expert, but I've owned 3, used a couple others, and been using them almost every day for approximately 6 years.
This is not the experience I'm used to.
But that's just the switch. Obviously the make or break of a keyboard, but switches are still personal preference.
The rest of the keyboard is well made, solidly built, heavy, inflexible, attractive, and professional.
The only real question I have is why not a proper Cap/Scroll/Num lock light setup? It's meant to be a professional keyboard, why can't we get a simple, informative light display for the people that constantly use these functions? Why do we need to instead waste space on a Windows lock that no one in an office environment would use? Why only two lights when you could easily fit all 4 if you wanted to?
I'll use it at work for awhile, but I already expect to get fed up with it and replace with the MasterKeys Pro M.
