Cherry MX Mechanical Keyboard Switches Compared
crookedvulture writes "Keyboards with mechanical key switches are enjoying a renaissance of sorts. They're prized by gamers, coders, and writers alike, and Cherry's MX switches are the most popular on newer models. There are MX blue, brown, black, and red switches, each with a different tactile feel and audible note. This comparison of four otherwise identical Rosewill keyboards details how each switch type feels and sounds, complete with audio recordings of the various colors in action. Recommended reading for anyone considering a mechanical keyboard or one of the Rosewills, which cost about $100. Looks like the removable USB cord on these particular models is prone to breakage."
Sounds like an ad, but seriously I found the best advice there.
from the company that holds the original design patent from IBM for the Model M, and inhereted the process from Lexmark. The keyboard is still built and serviced in Lexington, Kentucky. They ship internationally. have a nice rennaissance.

Good people go to bed earlier.
Hands down the best set of information have ever seen about mechanical keyboards was this forum post on the topic it has everything you want to know about the subject.
PS/2 has unlimited simultaneous keypresses (n key rollover/NKRO). USB, depending on where you look, either cannot, or needs a workaround to do more than 6 keys and a certain number of modifiers, generally 4 (shift/alt/ctrl/super).
Keep on knockin'

Accurate, and, on top of that, USB is polling based, while PS/2 is interrupt based. USB will check the port every "n" milliseconds to see if there's data waiting, while with a PS/2 keyboard, when you press a key, an interrupt is generated. The delay is very short (depending on how often a given keyboard's driver polls, it might only be 10 milliseconds or so), but it's worth noting.
PS/2 is still significantly better than USB for keyboard technology. But USB is usually good enough if you're not a gamer.
It is worth noting too, that just because you have PS/2 doesn't mean you have NKRO automatically, as depending on the technology 'underneath the hood' of a keyboard, it might not allow certain combinations of simultaneous keypresses. But that's an issue that's resolved by getting a mechanical keyboard, since they have the individual switches.
Shameless plug: Steelseries 7G. It's a big investment for a keyboard, but it provides NKRO, is a native PS/2 keyboard, is well constructed, and has audio jacks and USB ports on the keyboard, as well as a removable plastic wrist rest.
In my humble opinion, ergonomic keyboards are a really stupid response to most typing RSI issues, and it's probably a better idea to get a keyboard with proper keyswitches - all the ergonomic boards I've touched still have the same shitty membrane switches.
90% of the 'ergonomic' keyboards are only ergonomic because their marketing department decided to call it that. There's no actual testing, no actual thought on what would help the typist, they just copied what everyone else calls ergonomic.
If you are going to get an ergonomic keyboard, look for the ones where they actually thought about it - they'll cost more, but they'll actually be good as well. Personally, I use a Kinesis, and it's very good. They also all have mechanical switches - some models even offer a choice of which switch you want.
On the other hand, you'll never find them in a store...
'Sensible' is a curse word.
