smart thinking!

"" Start with servers. That's where Unix has already been, and people are willing to pay for
reliability and support. ""

People are willing to pay for "SERVICES" that they could not do by themselfs.

Buying a "box" and installing something with fancy guys that even a child could do, can never
be a sustainable business model IMHO... yes MSFT... but they will get their day of
recognition.

You could start with Desktop for that matter. 

"Support":You get it relatively big, and avoid the SOHO and the small business that don't have
a IT department like the plague, or you can get toasted very soon, even if you have the best
servers and the best technicians in the world...

Because very soon the bosses or someone very close, would be "making" changes to your server
configurations and blaming troubles on you!... and you shouldn't get deals where only you have
exclusive access to root, because then expect a real flush of calls at the most strange hours
and days!... and for the most stupid reasons!... they own you.

Why do you think MSFT never really got on that support business model? 

Unless you get it big, and only do real companys, support on servers is not a safe bet... but
is a temptation because the small fry represents almost 80% of business opportunitys out
there.

"Web services": Software installation can be a web service if made from  source code and
online as example... everything that a software applications can offer from online is a good
bet. Servers are there with "hosting", but believe desktop can be much better, because the
target audience can be several orders of magnitude higher.
