That's pretty much how it's been for me. I got the Steam Deck mostly for if I go on a trip, since I didn't use my Switch much because my PC library is too huge (thanks Humble) and I didn't like re-buying games on the Switch.

But I've found that the Deck had become my primary gaming platform now, and I use my desktop pretty rarely. Like you said, gaming in bed, or on the couch while my SO watches a show is a lot nicer than in my office. Being able to suspend games has been fantastic as well.
