Most often not. The big bosses (which do most decisions yet are not
always the cluefulst wrt. tech) look after "certification", the
"enterprise" sticker, and the correct blame policy (if it breaks, you
can kill <Vendor>; if your linux box breaks, you have to fix it
yourself). And here's an example case that it's not always optimal.

A $2k core router once died of the HD (sounds similar eh?), it took
the vendor 27h to replace it (and their office is just 500m away),
while if could have swapped the faulty disk ourselves, it would have
only taken as long as the disk copy takes (38 minutes for 80 GB at a
transfer rate of 35MB/s).
