It's interesting, though, to see the co-evolution of the Atari design strategy in the 7800, Amiga, and Lynx (the former explicitly being a souped-up 2600 and the latter two sharing design team in part). By the time of the Lynx there's a clear bias in the featureset towards "lots of powerful sprites in a fixed memory layout", so the alien nature of the earlier systems is mostly gone and it's become roughly as straightforward as a Neo Geo, plus a few little surprises like the retention of the old Atari "LFSR distortion" sound effects in the form of programmable timers as something you could opt to plug into the audio(which like the Amiga, is 4 channel digital, but the sound driver used in most games biases towards chiptune sounds).
