I find there are two sorts of people when it comes to monitors, namely those that:
a) Like to only see what they are working on. Can get overwhelmed by too much information - feel cluttered.
b) Like to see it all and instantly go to any part of it.
The former obviously have cheaper monitor requirements, while for the latter, there are never enough pixels!
If you have been putting up with a 14", you possibly have been content to be in the former. But if you are tempted by comments here to expand your pixel horizons, perhaps you should try and see what it looks like in reality. One of the musos on our CD, who was used to Logic at 800x600 at the time, did not like my setup that was a then modest 2 x 1280x1024 - too much info for them! You may still prefer to do the clickin’.
