[bug#58357] [Patch staging ] doc add a recommended system in 'Hardware Considerations'

[pelzflorian (Florian Pelz)]

Hmm Joshua, recommending these thinkpads may be good or may be bad.

Off-the-shelf hardware too often is at odds with freedom, and newcomers
underestimate how hard it is to find hardware.

For graphics cards <https://issues.guix.gnu.org/36786> “Warn of AMD GPUs
unusable with Guix System” is related.  As Ricardo said there, we do
point to h-node.

It would be bad to make recommendations that end up not working.  I have
doubts if new Intel GPUs is a safe advise.

IMHO ARM and Power need not be mentioned so explicitly.  On the website,
there is no Guix System download link for ARM except the Pinebook image
(I don’t own a Pinebook and can’t test that).  Guix on ARM works well,
now that rsvg works on ARM.

And once there is a new release, bordeaux will be enabled by default,
then Guix on ARM will be much better even by default.
