I've received this wonderful news this morning (it's not an April's fool joke): Sharepoint Designer, the tool that every Sharepoint developer must have, it's now totally free.
Personally I love Sharepoint Designer: this is maybe not the best and intuitive tool for editing and designing a Sharepoint site (layout), but it's an unvaluable tool for quickly build workflow-enabled applications based on Sharepoint (no Visual Studio or particular proramming concepts in order to create a workflow).
Long life to this tool, expecially now that's free for all...
