When docked, the Deck works great as a desktop PC. But not as a laptop. It’s too much to carry (lapdock + deck). The lapdock would be more suitable for your phone.

Thanks for the advice. I’m going to find out for myself either way though.

I have a large backpack and I’m used to carrying a lot of weight. I often carry a laptop + Nintendo Switch + battery pack and a bunch of misc stuff. So size and weight will be fine.

And part of the plan is that on days where I don’t need a full Linux OS, I would only take the lapdock and indeed use it with my phone. Thus my portable computing options are a lot more modular.
