Is a Raptor Blackbird (or other Power machine) a good general-purpose desktop?

[Lionel Élie Mamane <lionel@mamane.lu>]

Would a Power-based machine in general, and a Raptor Blackbird in
particular, be a good freedom-respecting computer to run a Debian
desktop?

Or will I have "many" problems like the one described in
https://www.talospace.com/2023/02/firefox-110-on-power.html
that Firefox WebRTC doesn't work on Power?

I don't particularly want to get deep into being a porter, but I want
a good desktop to run XFCE, emacs, mutt, gdal, Firefox ESR, etc,
developing my pet software, maybe get back into LibreOffice (a beast
to compile...)  development and/or become active as Debian package
maintainer again.

Is there any other Power-based machine that I should consider?

No candidate laptops I presume?

Thanks in advance for your advice,
