It's actually worth it if you have any kind of a commute. There are a lot of very fun games for it. And it's nice having a thing that isn't connected to the Internet to avoid the temptation of doom scrolling.
I bought mine pre release so it was like $50 cheaper even with the cover I think, but I would still pay the increased price for it. I thought it would collect dust, but it really is a great way to pass the time on the train. It scratches the original Gameboy itch for me without the needless stares from actually carrying a Gameboy.
I just wish they would release the docking station for it. I charge it next to my bed, so it could serve two purposes.
You'd farm more aura with an ereader on the train
