My eyes don't weigh much, but the mount that they are attached to is a bit on the heavy side. But I can still fit all of the equipment into my car without too much trouble and drive it out to a dark location. Set up time is a bit quicker because my retinas don't need to be collimated, just dark-adapted. Also, aligning them with the North Star is pretty much intuitive now. They don't use a worm gear-driven equatorial or German mount though; instead, they have a vestibular mount and a muscle-powered tracking drive. I have had this system for quite a long time, and it has served me well. I do need to upgrade the optics about every ten years or so in order to maintain quality, though. My system has a very stripped-down and simplified "astronomer inside" software program that will be gradually upgraded as time goes by (I hope). Pivoting my lenses across the sky to observe various phenomena is a breeze - even easier than using a Dobsonian. But it takes my software program awhile sometimes to pinpoint the desired object and get it centered in my FOV.
The apertures of my naked eye 'scopes are the major limitation, though. They just don't collect that much light, so observing deep-sky objects, splitting binary star systems, observing comets and asteroids, etc. are all a real problem for them. On the upside, though, the image post-processing software that is built into the equipment can't be beat, and it is upgradable. And the system comes with an enormous amount of storage pre-installed.
Finally, it has very advanced networking capabilities built into it, and it can automatically establish a wireless connection and share information with other similarly-equipped systems in its immediate vicinity.
