Mouseless and WIMPless desktops are great. I've been using ratpoison for the last 6 months or so and I love it, previously I was using ION3 for about a year but I ended up not using the tabs at all, just having everything in fullscreen and using the hotkeys to switch between them. Of course it wouldn't work for everyone but when 99% of your computing time is spent in Emacs and Firefox it really does make sense.
I've tried Conkeror and while I like the concept and can't really find any problem with the execution I just don't get on with it very well. Being an Emacs user I feel compelled to ignore Vimperator ;)
The ' key in Firefox (search for links) is great for navigating around without the mouse. Not that I'm religious about non-mousing of course, sometimes (especially during idle web surfing) it makes sense for me.
