Wow, so much stuff to discuss going on here!
But first of all thank you very much Dr. Dietz for clarifying my question!
And, damn the marketing people!
Wherever they are they never tell what really matters and just put up useless nonsense!
Does it hurt to add a one-liner or just a few words like "USB full-speed"?
You know Logitech Rumblepad2 boasts its accurate d-pad but they never talk about its durability! Transfer rate of 1.5 Mb/s on USB low-speed is complete bogus! And... oh, well, whatever.
And a few more to add..
Actually, no: PS/2 converters are notorious for their 6KRO.
It doesn't matter my model F is virtually NKRO, any convertor that hasn't got a special driver will only pick up the first 6 keys.
There is an exception I know of; the DRKBCN keyboard converter by Dharma Point, which seems to use the standard USB HID driver and yet it is 10-key rollover capable. Though the gimmick behind this looks tricky indeed. Also it's a bit expensive.
So, short answer - SideWinder X4 is a membrane-based keyboard that easily meets your simultaneous key pressing needs, and sells for about the price you want.
Ah, that should be true but the smaller ESC keys on recent Microsoft keyboards were deal-breaker to me.
Also, if I'm allowed to say, I'm a bit ambivalent about the "eat your own dog food" saying ...or was it just inside MSKK Japan? Anyway, although this is indeed a good thing to remember as a sharp, effective warning on quality control and moral standards, it still doesn't sound like they're aiming at higher quality standards. At least I'd insist that Microsoft should improve the "key feeling" on many keyboards for better customer satisfaction - while most will just tolerate, I feel it's just pretty much too mediocre.
The uTron is pretty damn sexy. It also costs a pretty damn sexy $500 (just like the M15 if you can find one).
Besides its price tag, you should watch that the key size is smaller (17mm) than your standard keyboards (19mm).
