Yep that's one of the first few thoughts that came to me, I thought it was more of a gimmick then anything, or the cool factor, yeah I personally did not back the Kappa thing yet (really wonder why they called it that too lol since Kappa can mean a troll thing :P) and not released until March, that's a good 6 months away, will wait and see, however if it does work and can print curves etc all the tricky stuff, will be very interesting, cause it only requires like half the parts compared to a cartesian, and seems easily upgradeable for a bigger print volume, but only half the price ish? we'll see.
