I would guess that they'll be sourcing a next-gen RISC-V processor ASAP, since those will enable virtualisation. If they stick one in a laptop shell I'd probably buy it pretty quickly. Doubly so if it has EFI.
I'm sure I'll get shouted down for this suggestion by the haters, but I'm going to make it anyway because it's actually really good:
Use an Ubuntu LTS flavour like Kubuntu. Then, add flatpak and for apps you want to keep up to date, install either the flatpak or the snap, depending on the particular app. In my personal experience, sometimes the flatpak is better and sometimes the snap is better. (I would add Nix to the mix, but I wouldn't call it particularly easy for beginners.)
This gets you:
A reliable Debian-like base that you only have to upgrade to new releases every 2 years
Up-to-date apps, including confinement for those apps
New kernels every 6 months (if you choose - you don't have to, though)
If there were an occasional thing where I looked at it and thought "wait, is this Loss?" that would be funny. But I see them way too frequently for them to be funny. They need to be subtle and occasional, taking one off guard. Instead they're frequent and unsubtle.
And they're providing Ubuntu for free. If you were a paying customer and the contract you'd signed with them said they'd provide Firefox as a deb, that would be a different situation.
The moment I can get a laptop-style RISC-V device with virtualisation support I'm doing it. Double bonus if I can actually use it as my daily driver.
