I take my Deck with me when I travel. The case is a little on the larger side, but it fits in a backpack under a plane seat. I do tend to have the opposite problem with the switch though, my hands cramp up because the joycon grips are so small. Battery life is an issue though, I can get maybe 3 hours out of it if the plane doesn't have an outlet.

It is a little hard to call the Deck a platform on its own because the library is all borrowed from an existing client and Valve doesn't really make games anymore, but for people who have a PC library or are looking to start one and don't necessarily have the money to throw at a whole gaming PC, the Deck is a solid choice for something portable-yet-powerful - it's good enough to run Elden Ring pretty stable. It's also really good for gen 6 and older emulation, both because the hardware is capable and because Valve doesn't give a fuck what you do with it.
