Why use Solaris? It's for the Application support!

Once again Solaris 10 (on either Sparc or X64 platforms) features a larger collection of available third party ISV applications than the competition. The numbers speak for themselves. Want freeware? Go to blastwave.org or sunfreeware.com
Why should you care?
When choosing an enterprise operating system platform, you need to be sure that you have the widest choice of workloads available to you. Add that to the fact the Solaris 10 is developed as an open source project, runs on commodity Sparc and X64 hardware and is free to download and the choice is simple.
