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.
That’s a shame, my favorite way of gaming on the deck (outside of some console port games) is Bluetooth mouse and keyboard, I play 4x and grand strategy games, along with many games that are “have not been tested for the deck”. This new thing looks like it would be a huge pain because you’re either going to have to play it while looking down at it on a hard surface, or you’re going to be imparting motion on the device every time you try to use the keys (or the keys will be so soft that they’re prone to sticking/errant inputs).
My only trouble with Bluetooth m+kb on the deck is some games refuse to acknowledge you’re not using the controls, and will pop up the keyboard interface every time a text entry box is opened, that’s annoying but most games don’t force that.
