I have a MacBook Pro with a 30" display and I still wish for more
screen space. I keep TextMate open in a window that is about 1/2 the
screen. The other half gets about 2-3 Terminal windows for the server
and general command use. THen there are numerous browser windows and
such that are in front or behind as needed. I would like a second 30"
to put all the reference material and the browser window I am using
for testing. That way I could look at it all at once. If Apple
announces new displays soon I may get there. At the same time, it is
possible to work on just the MacBook Pro screen when traveling, I just
do more window management.
