recently my wife want to go cordless on she desktop . I pass on my Logitech MX3200 keyboard and mx600 mouse combo , I have use this combo for a few year and be quite happy with it . so far the new mk700-m705 combo have be great . mk700 keyboard be quieter than my previous mx3200 and I like the look and touch of the key . I be a 2 finger peck typer so anything a real typist would find useful I can not comment on . there be a few feature on the mx3200 that the mk700 lack but for my use it be very adequate . the quick scrool feature on the m705 mouse I find very nice and overall I like the mouse also . the one point of the m705 mouse that I find lack be that the side forward and back button be not stick out as far as I would like and I have to search a little to find they where the same button on the mx600 be easier to locate . overall I be happy with the combo . also the looooong rate battery life be a plus if it prove to be true .
