I work in municipal government, and I just renamed the shortcuts on my work computer to avoid having to explain it to another mayor or councilmember. I think they're adding Photoshop to the bufget anyway next year. GIMP is good for free, but I have to admit Photoshop really is the king of photo editors.

I do really like Inkscape though.

The FOSS software I find to be the most impressive, however, is QGIS. I have ArcGIS and QGIS both installed on my machine and use them both heavily. For data processing, I usually go with QGIS, but then I make most of my deliverables in ArcGIS because it has a way better layout editor and lots of other software and angencies require me to use ESRI REST services.

But I can go with the cheapest ESRI licenses because I don't have to pay an extra 4 grand a year for the "Erase" tool when I can punch a hole in a shapefile in QGIS for free. And I openly said as much in my last meeting with ESRI when they were trying to get me to upgrade.
