Well, I was finally able to see what the WSXGA+ Hitachi screen looked like. Based on everything I've read on this, and the official Dell forum, I was expecting it to be really terrible, but to be honest, it wasn't.
I didn't play with the machine using Excel or surf the web that much, but the ghosting was barely noticeable unless I was dragging the scroll bar to read a web page. I don't do that anyway, so it doesn't matter. I did notice that when running a program like AdAware which displays the file name of each individual file as it is scanning, that the names tended to "mesh together". Not really a problem there either.
Loaded up a couple of DVDs and found some action-intensive scenes to see how bad the ghosting would be, but again, things were fine.
The one problem that does exist is the light leakage at the bottom of the LCD. Only noticeable against a black background though and not quite so bad when lowering the screen brightness a bit. I didn't like the brightness all the way maxed in any case. I put on a widescreen DVD, and without mentioning anything to her about the "problem", I asked my girlfriend to watch it. She didn't even seem to notice the leakage and was quite pleased with the performance.
Overall, I am happy to report that I was pretty pleased with the machine. It definitely isn't perfect and the screen does have some issues, but it is more than useable and the problems can be avoided if you change your useage habits a little e.g. scrolling a page at a time instead of dragging the bar. Maybe, I'm not as picky as the rest of you or don't have quite the need everything to be absolutely perfect, but if it were my machine, I could more than live with it...
