Still incredibly worth it, IMO. The Deck is some of the most fabulous and exciting hardware I've seen out in the last decade, perhaps only trumped by the M-series Apple chips.
It's genuinely great hardware and a great experience. So much so (and because Windows is such a shitpile) I actually moved my Ally to SteamOS too. No regrets.
I think a big part of this is that many (most?) modern games are designed to be played on big screens at a distance (e.g. TV <-> couch). The apparent size of the display in that scenario isn't much different from a Steam Deck held naturally.
I just wish the Deck had VRR. That and the general lack of power are my only real issues with it, and the power isn't that big a deal given the massive back catalog it supports.
