The Abacus is portable but its by no means light. Real wood, real metal, TFT touch screen display, a powerful internal amplifier and speaker system, and a nice feeling keybed makes it heavier than a plastic toy keyboard but it's about the same as a Yamaha Motif XS88 which many pro's gig with. The Wersi Ikarus is lighter if you need more portability but its also very well built so don't expect it to weigh 30-35 pounds.
