The formatting is messed up. . .

• Enforced, costly upgrades (.doc to .docx).
• MS Word and Powerpoint are infamous for compatibility/formatting problems
  • different versions; different platforms/OS.
  • proprietory format — OpenOffice does its best, but. . .
• Leads to problems:
  • Two or three people working on a journal article/paper;
  • presentation nightmares!
• LaTeX produces identical results on MS Windowz, Linux and OS-X.
  • Example: highly professional presentation produced by using Beamer.
