The big problem with windows handhelds is battery, there is a huge difference in consumption. I highly doubt that “most steam deck purchasers installed windows” (if that’s what you meant), you need a high technical level to do so and people are used to being limited to a single store in a console anyway.
Oh, sure. Agreed that at the time the proton Linux ecosystem was pretty under developed.
But to be excited now about a windows handheld is a whole other story, specially because of the battery as stated.
Unless you want to play TFT on the handheld for some god forsake reason I see no point on it being windows. But I ditched widows for all my PCs and I’m very tech savvy so I’m biased.
