I liked so much the way old Blender 2.41 Quickstart presents in a nutshell the basics of Blender. I teach Blender so I know how valuable are this kind of resources when we are on thight schedules. We need to boost the ability of the students in basic principles so they can dive more easily into other concepts not so elementary but important.
Again as a teacher, 2.5 releases were a challenge for me. So I prepared a new version for 2.5 releases of Blender. There are no big changes respect the old version (Blender is still Blender!); I did basically some corrections and additional informations on ways to do things in Blender 2.5x. Hope you find useful, be in an education context for your students or if you are just starting in learning Blender.
My english is not my strongest skill, or I could leave away things you find relevant, so feel free to improve it.
