You won't be disappointed. The Steam Deck is bad ass. I don't even use it as a handheld I just dock it and use it like a PC.

Does it run most things fairly well? Any little cons that it has?
It has so far run everything that I have thrown at it with no trouble. There are some issues with some games if you use it as a handheld like small text etc. But docked with a monitor, mouse, and keyboard it has so far been plug and play. Zero cons in my opinion. I reserved early so I've had mine for some time. I'm still amazed by it.
Damn alright that makes me even more hyped to get one. Yeah being a very causal not a lot of time to sit and game it seems like the perfect fit.
