Typesetting Equations in Word

I've done some experimentation with mathematical typesetting in Word. Here are my conclusions.

1. Word 2007 has a new equation editor (Insert tab -Equation). It is easy to use and supports keystroke shortcuts; for example "\sqrt (x / y^2 \pi )" will be nicely typeset with fractions, radicals, and exponentials.

2. For more complicated things like lining up equations at their equal signs, I'm still prefer the old Equation Editor. (Word 2007 treats math equations as text, which is good and bad depending on whether you want your equation to be word-wrapped.) Fortunately, the old Equation Editor is
available. Here is a web site that tells how to install it (I'm not positive that I needed to do this step, but it didn't hurt):

And here is a web site that tells how to put an icon on your QuickAccess toolbar atop Word for instant access to Equation Editor.

3. Finally, and this is the key element for me, if you convert Word documents to PDF using Word's built in PDF converter (which I do all the time for posting documents on the web), Word 2007 equations look positively horrible, whereas the old Equation Edited equations look great.  The worst conversion results from first converting a .docx equation to .doc and then doing a PDF conversion.
