When a person must edit a document, it normally means changing some text. Which could be (interestingly) bolding a word. Or using the same font that is being used all over the document.

Now if you wish, I can send you a PDF and you try to do that simple task. Especially in the newest Adobe Acrobat.

But most probably you have some PDF documents yourself around.

I really hope you will somehow grasp the difference between "normal" editors which allow you to simply select the text and bold it and the worldwide know tool Adobe Acrobat where you:

1. Open the document
2. Wait for all the wonders and boxes and messages to appear so you can close them
3. Click on "Edit" and wait that it turns everything on again
4. Add a text box and type something in
5. Try to figure out how to change the size of the font in that box
6. Still trying
7. Still wondering
8. Still researching
9. Giving up
10. Leaving it unbolded and just save and send

It is really amazing how such a huge development team can come up with... this new version.
