Not a huge fan of going bigger with these, it looses it's biggest treat - portability (already the og switch was big). Pocketability is out of question (besides maybe Switch Lite), but this is almost like dragging a small laptop. Would rather have something like GPD Win Mini or the 10" max variant than this...
The other disadvatage which comes with it is weight. Like all the x86 handhelds which you have to prop somehow because they are too heavy(uncomfortable) to game for longer time just holding it.. This is subjective, true, but still I would guess a big deal for more than just a small group of users..
