If you are in IT professionally (coding or sysadmin) you will be staring at monospaced fonts for many many hours a day. So it's probably justified to spend 2 minutes picking a very good one. It can make your work (typing ; ) just a little bit more pleasing.
The Inconsolata font by Raph Levien is considered one of the best programming fonts by many.
You can download it and install it yourself
