generic hardware not counted

We have bought many servers destined for Linux but never ever have they shipped with Linux. We
also have converted old Windows boxes to various tasks like firewalling, proxies, ftp and so
on. 

Im pretty shure IDC doesnt count appliances either, even if they are big NAS servers with
Linux in them.

What theese numbers can suggest is also that more people buys white boxes and use them for
Linux. That would be a very high grade for Linux as it shows it demands less support from
vendors than other operating systems do.
