Hah! I had a gig in that building (6116 Executive) when I was a consultant... writing billing systems for a phone company right after the Bell breakup.
I've been using Fedora exclusively for 4 or 5 years... Linux in general since 1995 (slackware on a mountain of 3.5" floppies!!!)
I love it because it allows me to get the most out of my machine. I've been using xfce and like it everywhere. Most of my work is on Linux machines of one flavor or another (mostly RHEL and a few Ubuntu) so it makes sense.
If I absolutely must do something with Windows, I have a vm that I crank up; then I can edit MS Word, PowerPoint, do my taxes, or update my GPS (Win only updater). I'm trying to convince folks at work to move to Google Docs with some success.
I won't switch to anything else any time soon; Linux does everything I need!
I may switch from Fedora... the continual update process is starting to feel like a treadmill... sometimes the version updates break a lot of things. I may switch to Debian to have a stable platform that doesn't go crazy with updates like Fedora; I've been playing with it on a vm and it seems fine.
I have a Chromebook in the kitchen for web browsing, checking email, etc. and it's surprisingly useful. I couldn't live with it day to day, but I've started to carry it while on the road more often; it's very small, light, and the battery lasts forever.
