I liked KDE when I first tried it in the late 90s, but never loved it. I've been living in Gnome since switching to Ubuntu in 2005 or 2006.

Whenever I try it after a hiatus, KDE always feels too visually busy. Little things seem to lack polish: the fonts, the stock clock app, things like that. The file manager is nice, but these days most file managers have a decent baseline level of functionality. (It's not the 90s anymore.) I also like some Gnome apps better: the system-monitor panel applet and terminal for example.

Unity and vanilla Gnome 3 are atrocious, but Gnome3 in the latest Ubuntu with the 'gnome-classic' session is basically Gnome2 with bug fixes. With two panels on the bottom (one with a window list, one with menus, app launchers, and widgets/panel applets) I have the familiarity of KDE (I can't stand the mac-style menubar-on-top layout) with the more-pleasing-to-me visuals of Gnome.

A coworker of mine gets stopped by TSA goons at T stations all the time. Every time, he politely and firmly tells them "I do not consent to a search". They don't let him on the train, so he just walks to the next T stop and gets on there. (It's very unlikely you'll be stopped at two consecutive stations.) He usually tells the goons he's doing this too, but they've never followed him or radioed ahead, despite often threatening to do so.

TLDR: Say "I don't consent to a search" and go to the next T stop. Optionally tell the goons how stupid there plan is, or don't; we don't need them smartening up.
