I have a Power Mac G5. I used three 17" CRTs on it
for a few years, but I got tired of the wide aspect
ratio of the resulting desktop. So, last Fall I got
three Dell 2405's. I have these set up in portrait
mode, looking a bit like a shoji screen.
To show off their capabilities, I:
* drag a browser window to 1200x1920 and bring up
a copy of (say) Google News
* start up the screen saver (three copies of
However, the practical benefits of having this much
real estate are that I can have several windows open
at the same time and that windows can have LOTS of
text in them. The former helps me to keep track of
large editing or development projects; the latter is
very handy when I want to get the overall context of
a large file.
For Rails development, I use a TextMate Project window
(and perhaps a file window or two), a copy of Firefox,
and a few Terminal windows. No overlapping of active
windows, but I do use window-shading and application
hiding to keep inactive windows out of the way.
The built-in graphics card (ATI Radeon 9650) on the
Mac supports two DVI monitors, so I had to get another
card (ATI Radeon 9200) to support the third one. It
isn't as fast, so I use it for less dynamic activity.
