touch tablet PC support among the best
I find Zorin OS Pro works well on a touchscreen tablet. Minimal user experience (UX) rough edges IF the macOS/Apple like desktop theme and "Use system title bar and borders" in Chrome settings, if you are using Chrome. https://gitlab.gnome.org/GNOME/mutter/-/issues/1603
Using that Apple/macOS like desktop theme means that the onscreen keyboard interferes miniminally app launcher so that apps that are filtered as you type in search will show mostly. With the other themes, either the keyboard or launcher in those is obscured by the other.
And for Chrome, enable that "Use system title bar and borders", so that you can drag Chrome windows around by the title pane. Otherwise the drag doesn't work.
It can be hit or miss with password entry to unlock screen and password entry to connect to a WiFi. The onscreen keyboard is available but typing doesn't always register in the password entry box. I haven't solved that and will contact Zorin.
Brightness controls don't work, again I'll contact Zorin.
But apart from that, among the best. My machine: a Panasonic FZ-G1 mkIII toughpad tablet PC, x86-64, 4Gb RAM, SSD.
I've already tried Mint, Elementary and Ubuntu. Mint had similar onscreen keyboard and launcher obscuring issues but didn't provide a theme that reduced these issues like Zorin does. Elementary was hopeless with the touch screen gestures: the settings for the number of fingers didn't match the actual. Ubuntu might fare better out of those 2 and closer to Zorin, with the Chrome setting but I moved on after some difficulties to Zorin and fixed the issues I could so far on that. Perhaps going back to Ubuntu to try these might have a positive outcome.
It's really great that Zorin is taking user experience (UX) / usablity really seriously with a Linux distribution. Rather than before that where maybe the usual thinking in the community is to make a virtue out of expecting people to fix it themselves and almost suggest that people are lazy for not wanting to tinker. If Linux is to have its year on the desktop (or tablet) then usablity does have to be taken seriously. Not half baked lip service: "it can do that a bit. But I'll go back to my gaming chair with it on a desktop and enthuse about various windows managers". Er, no actually. Expecting real life end use cases to just work is reasonable and benefits everyone. People have limited time and need that for getting real work done.
And tablet touchscreens with Linux is not a niche. Er, hello?! Apple, Android and Windows tablets show there is sizable market for such form factor. The 2 key benefits that a touchscreen enabled Linux like Zorin brings is that unlike Android, Apple and Windows support is not subject to their respective manufacturers. The other benefit, particularly compared to Apple and Android in particular is that running Linux enables the tablet to be a fully functional multipurpose machine. It can be used e.g. for dev work.
With older x86-64/amd64 touchscreen tablets not officially supported by Windows 11, the opportunity with Zorin OS Pro can be favourable for the above 2 reasons, as well as for the environment and the wallet.
