I’d probably say no from your replies below to people, OP. The screen alone isn’t worth several hundred dollars, and your main concern about portable gaming length seems addressable by an external battery pack and the carrying solution to include it with your Deck out and about for several hundred dollars cheaper.

Really it feels like you’re asking, is it worth spending all that extra cash to make your portable rig gaming setup less bulky when you’re gaming away from home. For me, the answer would be no and I’d put up with the slightly bulkier set up with the battery pack, and I feel like most people would be at the same place, but I don’t know your exact specific circumstances.
