I wouldn't really call something that cost > $1k quite a commodity (I think $1k is probably the ballpark of a decent living room projector)... but I agree with your sentiment - the value (value being a rough estimate of utility/dollar) of the hardware is skyrocketing and to me, seems to be far outpacing the development of software.
I don't have much experience with anything else other than LSX, Ildasos, LaserBoy - but have seen quite a few of the Pangolin Beyond tutorials - and one thing that that all of this software seems to have in common is that they feel stuck with 1990s MFC technology and really poor UI design decisions. I may just be extra sensitive to this area, because it is kinda what I do for a living - but I have yet to see a piece of Laser software that seems to be a "joy" to use. I mean with LSX, it is an extremely capable piece of software. And the stuff it does well, it does really well. However, it can also be extremely frustrating to use.
So hopefully the silver lining in the cost of projectors lowering, is that maybe that will increase the market for software and will enable some of the developers to spend a bit more effort on keeping up with software trends, instead of simply maintaining 10-20 year old technology.
I also am still dreaming of the day where one of the software companies sees the value and return on investment for making something cross-platform. Macs have ethernet ports and USB ports. Macs have up-to-date support for OpenGL - heck, the entire Mac OS relies heavily on OpenGL. So there are no technical excuses. Only business arguments - which given that lasers fall in the "multi-media" market cloud - is a market where Mac OS is already in heavy use.
