Java has been released by Sun as free software, licensed under GNU GPLv2. I'll vote this as the coolest event this year, for software developers at least. Java creator James Gosling's letter here. Sun is really re-positioning themselves in relation with the open source communities, and how much has changed over the last 10 years! They have now open sourced the operating system, liberated the office suite, freed the programming language and run-time, giving us the development environment and enterprise grade application server. Well done.
