TL;DR: Antec is going to be selling a Steam Deck competitive device, based on the Ayaneo Slide. The device has a slide up screen that reveals a keyboard, which is good because using desktop windows is much easier with a keyboard. However the device’s lowest estimated power draw at low/no load is 15w, meaning it will use comparable power to the deck running at max power. This means the battery life will probably be pretty rough when compared to the Deck. It will also likely have a much higher price point.
The thing is, none of the competitors and rivals are competitors and rivals to Valve. Every sold device that can play Steam games, is a win. Unlike traditional consoles, Valve only benefits from competition. The Steam Deck kicked off a trend and made handheld PCs popular for the “masses” (relatively speaking off course).
Besides that, any handheld PC with Windows is just not at the same level of Steam Deck. The few more games that are playable is a plus, but the entire system is such a downgrade for a gaming first device.
Valve has a larger goal though of making Linux a viable alternative to Windows for gamers. The whole reason valve has made some much effort on Linux gaming is because Microsoft scared them when Microsoft started making plans to block software installs from anywhere except the Microsoft store.
Microsoft has backed off from that plan some since, but many new new computers running windows are in “s mode” by default which limits software to Microsoft store only. It can be disabled if you have administrator privileges and know how, but it’s still an example of Microsoft trying to shift towards a future where all PC games have to be bought through their store.
This is also why steam jumped at the chance to work with Google on getting steam on Chrome OS.
Is S mode really that popular? I’ve never seen that in an enterprise setting. End users won’t want S mode because it will limit functionality.
Basically all cheaper laptops come in S mode now, and a lot of people don’t know that they can turn it off. They also made it where the only option for disabling it requires you to first create a Microsoft account and use the Microsoft store, so you’re required to use their preferred method for software distribution before you can choose to use something else.
It’s a lot better than Microsoft’s original plan for S mode, originally it was going to be a completely separate windows build, and end users would have to buy a new windows key and reinstall windows if they wanted to use steam.
I don’t think any of the enterprise builds of windows use S mode right now, but I’m not sure.
