IGN has a detailed hands-on which really boosted my interest:

The joystick layout looks funky to me, but apparently it works?
> However, as soon as I held it myself, the layout felt completely natural: the intuitive hand orientation when you grab the Steam Deck is more straight up and down, like holding the sides of a steering wheel, whereas with a controller your hands are at more of an angle. As a result, it’s easy and natural for your thumbs to reach the Steam Deck’s face buttons, D-pad, and thumbsticks.
And as a Mac user who has to load up Boot Camp to play most of my Steam library, a portable dockable PC is extremely appealing:
> As a result, in desktop mode the Steam Deck honestly just feels like a PC. The OS is Linux-based, but it feels largely familiar to Windows and is capable of running everything I threw at it from either platform. I played a bit of Factorio and Death Stranding with mouse and keyboard on a 32” monitor, and if it weren’t for the Steam Deck sitting docked next to me on the desk I would have forgotten it wasn’t running off a traditional desktop PC.
