Solaris is still a valid target. Samsung have several datacentres running workloads on Solaris to the point where it made sense to buy Joyent. Don't you think finance running exadatas are probably worth targeting also?
There is at least one very large bank (which I won't name) who is unable to move off ie6 for some internal apps which to my knowledge are still using this in some backoffices even today.... At least two years ago they were paying Microsoft less money than a rewrite would cost to support it so it kind of makes sense....
I only found that bad boy out after disabling some ciphers on some loadies which broke a lot of their stuff....
