awesome that is what I want do you know if they make them backlit?
Not the PLUM 96, but according to its advertising, it does comes with all the LED holes drilled and probably the circuit ready so you can modify it and make it become a backlit keyboard, though you'd have to buy the 3mm LEDs, diodes, solder them, test them and get some keycaps made for backlit keyboards "borrowed" from some other keyboard and put them on it.
Why didn't they make it backlit from the start? Well, besides the higher price, the battery (two AAA batteries) only lasts 1 week on wireless mode. Now, make it backlit and anyone can guess it won't last more than a few days or even a single day.
But well, the Morphling PLUM KB-87, which is PLUM 96's younger brother is backlit and it's the world's first mechanical keyboard that's backlit and wireless at the same time.
