I've been using logitek k310 wireless keyboards (and their cheap mini-mouse) for many years. Battery life has been the huge majority of the problems, and the ability to pick up the keyboard and take it the 3 or 4 feet to the machine without dragging a cable is like mastercard, priceless. Cross talk has also been a non- problem despite 3 machines in about 12 foot of space. Why the K310? Simple, square sided keys don't get jammed down by swarf near as often as conventional tapered sided keys where a bit of swarf follows the key down, then wedges it in the down position. Acer has one totaaly without a keymask thats pretty good in a swarfy environment, but it's A, wired, and B, twice the logiteks desk real estate requirements, and C, I've never been able to buy another like it, and finally D, it has so many extra keys you cannot pick it up and carry it without pressing some #@ multimedia key as they go clear to the edge of it. > > > > _______________________________________________ > Emc-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
