Oh Jafo, not Mitsubishi! I cringe when I hear Mitsubishi, but thats another story, you don't find the 1024x768 too over exagerated on that 19"?
Who said anything about being bigger for the sake of it - I am sure that you didn't buy that 19" because it came standard with your computer?
When I purchased my 19" it was with one thing in mind - more viewing area! In fact, over the past year I have come to see that purchasing ever growing monitors sizes is futile! Its become my personal belief that power-users should in fact relie on dual monitors to increase work efficiency but then again I have always been a little crazy when computers are concerned!
