I bought my wife a Steam Deck and she loves it, her biggest complaint is that it's a bit too big for women's hands. She isn't highly technical but I haven't had to provide much in the way of assistance, it largely just works.
I generally keep my Steam Deck at home and play from the couch. It’s awesome to be able to pick it up, play a game for 15 minutes, hit the power button to suspend. Come back later and pickup where I left off. The Switch does this as well but the Steam Deck supports games more my genre and style so it gets more use.
I think it's hard to genuinely appreciate how big the thing is until you hold it. Today I realized it's exactly the same size as my keyboard. And almost as wide as a 12-inch macbook.
