I be just browse around to see what keyboard be available and I be surprise to see the trusty Microsoft Natural Keyboard Elite still on the market . I have be use this keyboard every day for the past eight year and it have not fail I yet . what be especially great about this keyboard be its easy cleaning . after remove the 10-15 screw from the back of the keyboard , the key pop out in three section : left hand , right hand , and number pad . I scrub these with soapy water and a brush and rinse all debris away under the powerful spigot in my bathtub . I let the key section dry for a few hour and reassemble the keyboard . I have be do this every few month for eight year and I have yet to strip any screw or break anything . the last time I clean it , I use a little bit of rub alcohol to remove some of the palm oils which be embed into the plastic palm rest . this keyboard look as good as it do in 2002 , and none of the key have begin to show any wear either ! I have to agree with other reviewer that the arrow key layout be not the best . I remember use the prior model of the Microsoft Natural Keyboard about ten year ago , which have a better design with full-sized arrow key . I be consider order another one of these just to keep it in the closet in case the one I be use to type this review break , although I suspect that this one should last I 10-20 year give its current condition .
