Ajaxify Single Page Projects

Observations: This was an interesting assignment.  I had originally finished this assignment on Tuesday, but was having some odd errors.  A bunch of my tests were failing that hadn't failed before.  After struggling with it for several days, I decided to just redo the assignment.  Success!  Apparently, I had missed a step or two.  Had jury duty Monday - Wednesday and found working in the juror room not very conducive to good concentration.

Question: In the real world, how often is ajax used?  Did a little reading, sounds like it can help in improving performance.  What other areas would ajax help?
