Regular 3DS was tiny and $250. 3DS XL was $200 and bigger.
The OG Gameboy launched for $89 back in 89. Factoring in inflation that would be $186 in today's money.
The GBA launched for $99, which is $144 in today's money.
DS Launched for $149, which is $202 in today's money.
3DS's $249 is $284 in today's money.
Anyway, the original 3DS model was not priced to be successful. There's a long history of expensive handhelds failing. Even after the XL model launched, the 3DS still only managed to get PSP level sales due to its price. Had Nintendo just launched with the 2DS XL at $180, and a better launch title than OoT Remake it would have done at least PS4 lifetime sales.
