I just doubt the system would have had the power to last too long. It might have paved the way for the Studio III, had it been sucessful, but RCA seemed too half-hearted in its pursuit of the video game market for of this to be a possibilty. Overall, it is a fairly rare system since it never sold well. Chances are most people either threw their out or packed it away after they got an Atari. This means you're more likely to find one when you buy a house in the attic, shoved in a corner covered with mouse droppings and icky spiders than to find one in a thrift store.
Most collectors view it as a novelty, and that's a fairly accurate view.
There is little about the system to make it important, history-wise other than it was one of the first programmable systems. It has a slick, retro look to it and most collectors will buy one if they find one, but it's usually the first thing to go when they need to make space. The only other attraction the system has is because it was such a port seller, there is a definate, finite list of games for it. On both the left and right of the unit it has numeric keybads. There are arrows by the key to indicate there use as directional control.
