I have a gaming keyboard. It has a switch that turns off the Windows key and that's about all I care about, except every time I try to use the Windows key.
I don't, I just buy a new one. All I ask from my keyboard is that it isn't a chicklet, and that the keys are regular sized, no stupid arrow key designs or funky insert/home layouts. Unless you have magic non-shedding skin and hair this is not going to work.
I looked up some of the keyboards mentioned here because mine is starting to die after a solid 15 years of use. Why on earth would you ever need a $150 keyboard? Does it type for you?
