It shows that you took an extra year to write your dissertation. ;-)
Just kidding, but I got my degree 25 years ago, and at the time, the students who tried to have a perfectly typeset document spent a lot of time on that pursuit.
I used Bitstream-Charter [1] for my dissertation. It looks much better than Computer Modern.
My resume is typeset in Linux Libertine [2] which is used in this superlatively beautiful and elegant CV template by Dario Taraborelli [3]. Requires xelatex.
Apart from personal preference, why avoid Computer Modern?
