That’s unfortunate. It looks like Zotac is releasing a handheld that looks super similar to the steam deck. https://www.zotac.com/us/page/zotac-gaming-zone-portable-handheld
With all the Xbox game pass advertising it looks like it runs windows. Hopefully one of the handheld Linux distros will work on it.
Also take a look at: The Suicide of Rachel Foster
It’s currently 90% off on steam at 1.79USD
This also suffers from Microsofts consistent issues where they just don’t try. They designed them and didn’t do anything with them, they barely iterated the product. I happen to have 2 because it’s cheap. This is also an issue with the surface tablets. They have a stylus that works really well in art programs, but it absolutely sucks when you want to actually be productive with documents as in writing and filling out forms and not marking up PDFs. Same with the windows phone and windows ce, no follow through at all.
It’s going to be interesting when they finally kill all their AI integrations in windows. Microsoft similar to Google likes to build things and if it’s not an immediate success they kill it as fast as the can. Even faster than Google does.
A pattern you will see with Microsoft is they will build something, let it languish, build the next version, let it languish and then kill it. They are hella slow to react to markets or update their products, especially hardware.
