well...i actually have used 1024x1280 for some time now on my 18.1". I can see everything fine. really clear. and i can see a lot more things. However, my 18.1" brok recently, and i have a 15" spare. To answer someone elses question, yes, you can have 1280x1024 on a 15". Call me crazy (as im sure you all will), but i have been using 1280x1024 on this 15" backup for about 1.5 months, nad its been fine. I also used it a long time back on this res on this 15" before i got my 18.1".
yes...i like small resolution
