The device is meant to be used and abused. Play and charge on it as you want without regard to how often you do it. The battery replacement you might need years down the road is probably about $20 bucks.

1. The steam deck is not an investment so the fact it “depreciated” is irrelevant.
2. Your problem itself comes from a lack of self awareness. Not because of the market.
3. If you were happy with your steam deck yesterday, and not today because others can get it cheaper or a better version for around the same price, then surely you understand the issue given the “poor” pitty party you tried to throw yourself. Be happy for those that can now get what you couldn’t before. (And the second pitty party you threw yourself when you got butthurt at the replies)

Instead of fighting back at everyone, maybe in this case, consider that maybe they have a point? Maybe you can grow a little from this. Or don’t and just be mad at the world.
