And over here in Linux-ville...
My main distro is Arch Linux 64. Straight Compiz WM, no KDE or GNOME bloat; LXpanel and Tint2 systray.
I'm fortunate enough to have two monitors, so I don't have to get into the whole command-line-vs-GUI debate, I have both simultaneously. For CLI stuff I have Terminator, which allows me to split my terminal into multiple windows; in one I have htop as a sysmon, in another I exec
to keep tabs on temps (I OC), in a third term I have centerim for chat, and a fourth term for...well, terminal stuff. With transparency the whole thing looks straight out of
Minority Report.
OpenOffice.org has been kind of getting on my nerves lately; I have to keep a copy of MS Office in a VM anyway because school "officially" calls for .docx. Speaking of VMs I primarily use VirtualBox which has really come into its own after Sun took it over from Innotek; I still have VMware Workstation for the rare occasion that it can do something VBox can't.
PCManFM for a file manager, Transmission for a bittorrent client, nano/gedit, FF/TBird but probably switching to Opera, and...umm, that's pretty much it. My VMs have all the usual stuff; Ubuntu does some things better (or easier) than, say, Mandriva, and PCLinuxOS might be better still; since I test all these distros for my site I already have them handy. For the most part I take Linus Torvalds' advice and use the best tool for the job, open-source or otherwise.
