Blender can be used with a two button mouse comfortably. This part is wrong.: "Now for an important prerequisite: a mouse with an easy to use middle button."

Blender can be used with a two button mouse comfortably. This part is wrong.: "Now for an important prerequisite: a mouse with an easy to use middle button." You don't need a mouse with a middle button. Just go to user preferences, "File" menu, "Use preferences..." item, "Input tab", set radio button "Emulate three button mouse" on, Click button "Save user settings" in the bottom. Now alt+ left button will map to the same action as the middle button.
