[luau] Linux not an end to end Solution?

[Virgil]

Someone emailed me with this diatribe. Can someone point to me that the
below statement is not true?

Thanks, 


You're going to have a tough time showing that Linux is actually either
taking away marketshare from current Windows-based server installations
(because obviously clients are most likely going to be Windows in a business
environment (again, for obvious reasons), and Windows Server and Client
provide an end-to-end solution which cannot be matched with a Linux server
and Windows clients) or taking away from future Windows marketshare.
