HP USB Slim Business Keyboard
People may wonder who'll use wired keyboard, here is our OzBargainer's scenario
… My mouse is cordless, but not my keyboard. I occasionally do secure work (I'm a contractor to many companies), so a cordless keyboard is not permissible, as the "encryption" done by wireless keyboards is almost certainly weak encryption. So it looks like I'll have to replace my keyboard every year or so, or upgrade to one with a replaceable cord.
I found it's quite handy for pre OS boot-up BIOS setting.
Details of the keyboard can be found on HP web page.
or pay $15 via their ebay store…
