Since most of our tools (CRM, contact lists, account management, etc) are managed through web-based software, the availability of local apps are less important. KMail, Konqueror, KOrganizer, and Kate are the most used (roughly in that order). None of them have all the features everyone wants. But they are clean, slick, and have a consistent look. Lots of our work is done with non-KDE free software, such as StarOffice. But the workers don't like using non-KDE apps - StarOffice in particular has horrible desktop integration on UNIX.
Here's a funny story - when I was snapping a few photos to accompany this interview, I mentioned that it was an interview for KDE. One of the employees being photographed said, "What's KDE?" I pointed to his screen. "Wait," he said, "I thought that was Linux?" I spent a few minutes trying to explain the difference, but didn't have much luck. He did finally say, "Ohh...so THAT'S why so many of these programs start with the letter K!"
