I know I won't regret it later, but in a few days I'll have my first dream deck, even if it's just a refurbished one. I'm somewhat regretting the purchase now, but it's too late.
I usually have sticker shock and a little buyer's remorse after making a big purchase, but I've never once felt that with my Steam Deck (except that interim time when it was processing/shipping). I hope you feel that way, too.
If you divide out the number of entertainment hours you get, it will be worth it over time. I have probably 2,000 hours on mine. Insanely cheap vs. other forms of entertainment especially considering I already owned many of the games.
More of a sticker shock and buyers remorse thing more than anything. Even though I have more than enough money, I kinda felt like I was spending too much on a single purchase. Absolutely nothing wrong with the deck itself, just a me thing.
