this be my second Microsoft Natural Elite keyboard . the first one I have meet a untimely death when I accidentally dump a cup of coffee into it after 10 year of faithful service . the new keyboard have a even nicer touch , and the black color now match the rest of my computer component . the keyboard seem almost as if it be custom design for my hand , as my hand `` naturally '' fall into position above the key . I love the Windows key shortcut , which be a plus with all Microsoft keyboard , but I find a new undocumented feature , and a nifty one at that : the space bar function as a page down key , as well as page up when use in combination with the shift key . I be not sure if the older keyboard have this function as well . a nice add touch be that with the include adapter , you can use it with either a PS\/2 or usb port . I use the PS\/2 port to save the usb port on my computer for other use . Amazon 's price on this be the best I could find , and be a prime member , I receive it in 2 day , shipping include . great design , great quality , great price .
