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!"
