i'm using mine atm to make this post... works great, i have the 1.8ghz model from australia, not a single defect, i even double checked my pixels with that dead pixel program, and there's not a single one on the screen
the only two complaints i would make, would be a) the battery life isn't the best, but it can be remedied with the 12 cell battery, and b) the gfx card is awesome, but the resolution settings do detract a bit form this when gaming. i've noticed that on the native widescreen resolution, when playing anything based on the source engine, the antialiasing (even at full) is lacking at first i thought it was just the graphics card, now i realise it's the higher resolution, on the 4:3 setting for 1200 x 800, it isn't anywhere near as noticable, but this resolution is stretched... i know it sounds a bit sutpid, but if only there was a way to make the resolution not stretched, but have black vertical bars, playing source games would be that little bit better. (it does however run source games with EVERY setting at full, and a fps rate that often exceeds 60, so i had to turn on vertical sync to stop the tearing)
but these are both trivial, it's an awesome laptop, and doesn't look half bad either (this is where you can laugh at dell)
also, the 1gb memory on mine proalby makes a bit of difference, but in effect, this is my first time using a mobile intel processor heavily, and i'm extremely impressed, especially with its ability to multi task.
i give the 1.8ghz version 2 thumbs up, and the difference between this and the 1.6ghz, will really only effect you when u run big apps, like intensive games and all the rest.
p.s. r3c0gn1z3d, how much did you pick yours up in australia for, and where?
