So should everyone NEVER use it?

Can you ALWAYS get the same result by just using more A records???

e.g. Use 2 A records to set www.mydomain.com and mydomain.com
to SAME IP address without CNAMEs!!!

It's just more maintenance when your IP changes
Think of CNAME as a symlink, rather than a copy of the file all over the filesystem
