Deck just showed up. After spending a few minutes with it my excitement level is about a 0 for it. That video linked a few pages back it pretty spot on - "Look! I can play some of my games on a small screen with the occasional compatibility issue!"
I know there are other considerations besides cost, but Valve should have ponied up the $20/deck fee for Windows. That's more than worth it for complete Steam Library compatibility. I know there are Steam Deck Windows drivers but I am not sure if they are feature complete yet. Server/console Linux is great, but desktop Linux and gaming on Linux both suck (I daily drive Linux and have more issues/crashes on it that any Windows machine). I also overlooked the lack of a USB A port, which would have been nice to plug in a wireless keyboard/mouse to toy around with desktop mode on the deck with. I do not have a USB-C dock and will likely get one, but who knows when the official Valve dock will be available which means buy one now and buy the (presumably) better Valve one later.
I will say it looks and feels nice, but it has some flaws. It is fairly wide. It doesn't seem uncomfortable for me to use and hold but it could be for smaller people. The D-pad and the left stick are too close together, so I hit the stick when pushing the D-pad right. The cases seems nice, but it seems to have a recessed area on the outside bottom of the case to hold the charger (or maybe wired earbuds or both), but it is not deep enough (or the charger is too fat). It sticks out and
stops the case from laying flat (not my pic, and shows some sort of charger holder, but illustrates the point). Just bad design. That area is mostly covered by an elastic strap - a full velcro flap would be better to prevent anything from slipping out the sides. Or move that space to the inside of the case and the problem goes away. The included charger has the cable attached. This is the
kind of charger needed to store it flat. It would also be nice to have an appropiately located access hole to charge while the Deck is in the closed case.
Valve definitely cheaped out on the packaging for shipping. It ships in its case (with a paper sleeve and a plastic bag -
not my pic) and inside a fitted brown cardboard box, but there is no shelf/store box and no padding or protection between the shipping box and the Deck case. The end of my shipping box was crushed a bit, and I could look inside and see the Deck case. It did arrive undamaged, but I think there should be more than just the case to deflect any shipping force/damage.
PC games just aren't meant for the Deck form factor and control scheme. Same reason why the Steam controller failed. And Steam Machines/Steam Link. Unless you just want to run emulators, buy a real handheld console. To the shelf it goes. I must be getting old.
