Compared to some forms of entertainment, $180 for a few hours isn't that bad. A flight in a small plane would run you way more than that.
Then again, I suspect many raspberry pis meet the same fate; bought and played with for a few hours and then left to collect dust in a drawer somewhere.
to be pedantic, 0.1% of the planet is 8 million. There aren't a lot of non-essential products selling 7.92 billion of anything so this is an unreasonable bar.
(and yes, I have no regrets being pedantic to a comment that comes down to "remember that you are a niche").
WARNING: you will get addicted and end up spending $15-20k on a license.
