well none of the 5 dells I own are washed out.
XPS2 17" Truelife
M1710 17" Truelife
E1405 14" Truelife
Out of all of them I had 1 LCD isue (cracked) due to a bad screw. I have never had image quality issues. The one Sony Vaio I owned was nice, it just did not have the power I needed. The screen on it was beautiful...
taking pictures isn't really going to do any of the screens justtice unless you take 3 seperate shots with each one centered on the camera.
