I do now.
After killing off preinstalled programs (namely MS Paint and Kodak Imaging), I was in dire need of a replacement image viewer. I soon grew tired of waiting for the monster that is Photoshop to load up, only to briefly view a small bitmap image. InfraView proved itself to be the prefect light weight image viewer, with support for dozens of file formats.
Now all I need is an alternative to WordPad (*.doc) - Yes, I'm probably nuts for uninstalling it.
