I don't see the newer generation getting suddenly attracted by the primitive graphics. Only the nostalgic, hardcore retro gamers do really care about that. And these are the kind of people who want the exact real experience, which mean using a CRT TV/monitor and the real machine. Only concession they sometimes do is using a cartdridge with sdcard support.
And it is not like those old Ataris are rare and difficult to find which would justify the existence of alternatives. I see a few ones available for around ~50€ in the local market, less than half the price of that thing.
