if the wifi requires non-free software thats not a good thing
not too hard to replace with a libre wifi card but still
there a quite a few people (like myself about 6 months ago)
that would just install the non-free wifi blob
the GPU is not as big a problem as it will still run but only
without graphics acceleration so for a basic desktop user
this dose not matter too much but its not ideal
they do not advertise a free bios this is from there site:
"Free BIOS (Coreboot, etc.): Our computers are not yet available with a Free
BIOS, but we are very interested in offering that option in the future."
the Coreboot bios they offer will not be completely libre
they offer it as its a improvement over the factory bios
