I got my hands on a Duet 3 Chromebook tablet. I did consider grabbing the larger Duet 5 but I already have a 13" class device and as tempting as that big beautiful oled display is, I like small laptops. Really the perfect size for a computer, they shouldn't make computers any bigger than this.
Running Postmarket, incredible how little pain there was in getting this up and running, mainline on ARM has really come a way. I have wanted a little ARM portable computer for basically as long as I have known that ARM existed. The Snapdragon 7c gen 2 isn't fast but it's plenty, I think the biggest thing holding this back is video codec support.
Briefly fidgeted with current-generation chromeOS before doing this, I haven't touched ChromeOS in a while. I can see why you'd use it, it's perfectly pleasant as a system. High quality top-to-bottom integration, hilariously the chrome install even grandfathered in my ublock origin from my Google account so I had Adblock in Chrome on a Chromebook with zero effort. You can even install containerised Linux workloads with Google's blessing, if it's a personal system. If I wasn't a gremlin this would be pretty nice actually.
Linux obviously lacks some of the polish of more commercial operating systems when it comes to mobile support. Plasma's onscreen keyboard is functional but lacking, Gnome is better but only a little. Accelerometer and pen input work perfectly on Plasma, Gnome needs some transforms and udev rules that are mutually incompatible so I need to try and rewrite those. Honestly this is going way better than I expected. Better accelerometer support than my amd64 laptop, which has an awkward middle child of AMD's Sensor Fusion Hub that just never really got good driver support.
Had some mysterious crashes that seem to have settled now. I'll try and fill in some notes on the wiki and try to write some patches for the mobile tools. I'm not sure if I'm going to use Gnome or Plasma. I only briefly poked at Plasma Mobile, which is pretty good but too mobile for something this large. They're both pretty good in their own ways. Plasma's keyboard is actually more technically capable but it's a lot less convenient to deploy. I'll probably have to hack on either of them and I am much more familiar with KDE than Gnome. I also like KDE more but undeniably Gnome has benefited from Ubuntu's weird phone obsession.
