Buying a Steam Deck? You'll Want a Keyboard, Here's How to Pick One

howtogeek.com:

While the Steam Deck is the closest we’ve got to a gaming console out of all handheld PCs, I recommend grabbing a keyboard if you plan to venture out into Desktop Mode or use your Deck docked. Here’s how to pick one, along with a few recommendations if you don’t feel like window shopping online.

Bluetooth Connectivity Is A Must

First and foremost, make sure to get a Bluetooth keyboard, or one that supports 2.4GHz wireless connectivity, because having to hook a wired keyboard to your Deck every time you want to type something is not only a huge pain, but also requires a USB-C dock since the Deck only has a single USB-C port.

Connecting a wired keyboard when docked is an even bigger hassle, especially if you keep your dock next to your TV. I strongly advise every Steam Deck owner to go down the Bluetooth route.

While not perfect and with a higher amount of latency compared to the cable and 2.4G, Bluetooth connectivity is reliable and fast enough for both light and long typing sessions, as well as for playing most single-player games.

Those of you who want to play multiplayer games on your Deck, or titles that require as little latency as possible, such as rhythm games, should aim for a keyboard that supports 2.4GHz wireless connectivity instead. That's because 2.4GHz offers higher reliability and lower latency than Bluetooth.

A Foldable Keyboard Is Great for Steam Deck Owners Who Are Constantly on the Move

If you’re a frequent traveler and want a keyboard that won’t take up lots of space in your bag, check out foldable keyboards. They aren’t the greatest choice for typing and gaming due to their design, but they take much less space than even 60% keyboards, most models are super affordable, and virtually every foldable keyboard supports wireless connectivity.

A foldable keyboard is also a great choice for Steam Deck owners looking for a super-compact and affordable keyboard which they can tuck away in a drawer and take out for an occasional excursion
