Just wanted to give you a pointer to a great article by Jess Thompson from Gartner on GlassFish Portfolio. This article does a great job of setting up the case on why enterprises should look at open source (and why they shouldn't) and how GlassFish helps address these issues...
Give it a read and let me know what you think.
