Good link, oz.
My 2 bits:
The demonstrator has a huge sreen, so he sits on 1 view and toggles tags. Excellent when you have the screen real-estate to spare. That is exactly what tiling wms are about, and of course, multiple monitors.
I, however, have a 15.4" LCD screen, and only one of them. My eyesight is also not so good as I age. So I shift views all the time (with ALT-left and ALT-right), keep things maximized, and have tags that I don't mess with too much once I have things set up.
dwm rocks, even for me. It makes the best use of screen real-estate, one way or another.
