Very interesting to see that Windows 11 is slightly ahead of Ubuntu. Clearly the Ubuntu experience isn't that polished yet, as there are various driver issues. Still very interesting comparison. I sort of can't believe you can play Cyberpunk on this thing.
I think we have to give credit to Valve for making SteamOS as polished as it is. Even if you put a standard Linux OS on a handheld machine it's not going to be a giant success without software optimization
Glad to see the Linux numbers are looking pretty good right out of the box. I briefly tested ChimeraOS on my Ally but because it can't boot from SD cards I was booting via a USB card reader and that was causing issues. Hopefully I can get a bigger SSD soon and dual boot, as there are still some reverse engineering things I want to get out of Windows and with WiFi support not working in Linux it'll be a kernel release or two before it's truly viable it seems.
It's definitely not as nice as the Steam Deck because the Deck has touchpads. The Ally has a mode where the controller can act as a mouse but it's not great, and it requires the ROG software to switch between mouse and gamepad modes. Otherwise you're stuck with the touchscreen. I would recommend mouse and keyboard if you're going to be doing anything other than running the SteamOS/Big Picture UI (or the ROG Ally UI, but it's not great).
On Linux, I made a program that can use a touchscreen as a mouse that should be able to work on any device with a touchscreen. I originally made it for the PinePhone so that I could click on things easier, but with a few tweaks it would probably work on the Ally for a pseudo-touchpad.
