Feel free to elaborate on how the Deck is convenient to someone that isn't interested in playing on a tiny, washed-out 800p display with sub-2 hour battery life while playing BG3, and how playing on a TV is less fuss with the Steam Deck than the Xbox. Quick resume is a completely different topic that would be irrelevant, even if the Xbox didn't already have the exact same feature.

Then when you factor in the value you get from being able to play modern games comfortably while traveling

Worthless to someone that only wants to play at home on their TV, or isn't tethered to an outlet. It seems you're wholly incapable of comprehending that there are people with different use-cases and priorities than your own, and for those people the Steam Deck is a vastly inferior and costlier option. Buying the device that best meets their needs doesn't make them a fool. It's astounding that you don't get this.
