Logitech Releases a Smörgåsbord of Gaming Peripherals
 

Gaming keyboards come in all shapes, sizes, costs, and utilities. The multi-functional Z-board, with its game-specific overlays has had some attention over the years, as well as the Saitek Eclipse range, and Logitech’s own G-series keyboards.

The original G15 in the range offered a flip-up black-and-white LCD display, programmable G-buttons, a physical switch to turn the Windows key off, and on-board media controls. The G11 then offered everything the G15 did, without the display. The G15 revision 2 integrated the screen into the keyboard, and reduced the number of G-buttons. The G19 then became an LCD color version of the newer G15, with some other small enhancements.
