I tend to avoid evangelism of any sort these days, but if you are a unix weenie of any flavor and do not use screen then you are, quite frankly, not cool.
Screen needs some help to make it more visually appealing, so here's a snippet from my .screenrc. (Note: I lifted this off another website many moons ago. Props to whoever did it.) This makes a pretty blue bar at the bottom of your screen that shows you your different screens (analogous to tabs).

hardstatus string "%{.bW}%-w%{.rW}%n %t%{-}%+w %=%{..G} %H %{..Y} %m/%d %C%a "

Screen is very, very handy. It always surprises me that more people don't seem to know about it. It's far more elegant than any GUI solution; the real estate is minimal (and optional, actually), and being able to attach to an existing session is just the epitome of cool.
