Logitech Signature K650 Wireless Keyboard vs Logitech Wave Keys Wireless Ergonomic Keyboard
Get the Logitech Wave Keys. Unless you want a plain, flat keyboard for the least money — then the Signature K650.
Logitech Signature K650 Wireless Keyboard
A cheap, quiet full-size keyboard with a number pad, a built-in palm rest and handy shortcut keys. No backlight, and one device at a time.
Logitech Wave Keys Wireless Ergonomic Keyboard
An easy first ergonomic keyboard: a gentle wave shape and a cushioned palm rest, very quiet keys and years on two AAA batteries, for much less than a split keyboard.
