In 2004, Microsoft was granted a patent on using a double-click on "limited resource computing devices". As a result of this, some observers fear that any U.S. company which uses double-clicking may have to change their product not to use the technology, pay licensing fees to Microsoft, or give Microsoft access to intellectual property.
Lenovo does sell Linux laptops and then there is the HP Dev One. Also according to Canonical over 160 Dell laptop, desktop, and workstation models ship with Ubuntu preinstalled.
openSUSE does support FlatPak, just follow the Wiki entry. There is also a wiki entry about Steam
Blender is in the repositories. Also keep in mind that they stance about multimedia codecs is the same as Fedora. Please consusult this wiki entry for more information.
I have to say that openSUSE Tumbleweed is a fantastic distro. It is rolling release, but it is also using OpenQA to make sure nothing breaks during updates.
Hope this helps.
If you are familiar with Arch, you can use arch on your laptop.
You can consider Garuda Linux which is arch with a graphical installer, preconfigured DE and WM plus confirmation and maintenance tools. They also have a PacMan repository called Chaotic-AUR: a repository with huge selection of precompiled air packages.
They have - among others - Wayfire, Sway, i3WM and Qtile editions. You can try them out from a live usb and see what you think.
