Installation: Very simple install with helpful
	defaults.  Follows standard NCSA style
	installation.  Very flexible/configurable
	as well.

Reliability: I've run it on servers that get 		  
	millions of hits a week without problems, 
	ever.

Tech support: In addition to solid, 
	straightforward documentation and quality
	commercial support being available, Apache
	is available as source which makes solving
	problems much much easier.  Additionally
	newsgroup support is faster and more 
	reliable than any of the big commercial
	server vendors in my experience.

Overall: Apache is free, quality, flexible and
	extensible.  Overall an outstanding
	server.

As someone who has written numerous special
function servers, Apache's API and included
modules make for a high performance fast and
extensible server superior to _any_ other server I
have seen.
