Ok, so I've had my Dell (gasp) for a while now, probably about a year. (it was a gift thank you). But I've had my resolution set at 1680 x 1050 this whole time. Since I have an approximately 15" computer, whats the deal? Do 15" PB's just suck it up, or or they just different sizes. Why is my resolution able to be set at the same as for the 17"PB? Nice, i know, but I just thought PB's were top of the line, and my Dell wasn't, so why is mine better? This seems odd, so I guess my real question is are PB's behind, or is my Dell better than i thought?
