I’m sure some of you have a matrix of LCD flatscreens for your development display, but I work for a company that doesn’t think that’s a justafiable cost, so I’ve been using a 19” CRT with my Lattitude Laptop screen next to it as a second display.  Recently a co-worker quit and left behind a 21” monitor.  I snagged it and replaced my 19” with that, and I can really tell a different in readable screen real estate.  I’ve been using a 19” since 1998, so I notice the extra room immediately.
