On sibling thread I already mention the Surface Pro (convertible) at 12'' and it's 2880 x 1920. The next 2025 convertible that I found, Latitude 7350, is also 2880 x 1920 (at 13'', though). In fact, most of the 12'' convertibles with 1080p are either sub$800 (which I doubt this thing is) or come from Lenovo (whom you really do NOT want to compare with regarding screen quality -- https://www.notebookcheck.net/Enough-with-the-cheap-screens-... ).
And let's not get started on 12'' Android tablets...
That model of Surface is nearing almost 8 years old by now. Not current by my standards. I'm thinking about the chance of existing tooling still being around to make a screen and slap into a laptop rather than if it existed at one point.
But yes, considering that Framework's Chromebook is/was expensive (over $1k) for the class doesn't give a lot of faith that the 12in model would be any different. Though that was equipped with a 2k screen and had a 12th gen i5, so I genuinely wonder what kind of meetings happened to ship out a premium Chromebook (a segment that does not exist)
The last Surface model is less than one month old. The chassis was updated less than 2 years ago ( and to reduce the screen margins, no less ), and the resolution was improved again.
