well, hear out a guy who owns a WXGA laptop and whose brother owns a WSXGA laptop.
WXGA is easier on the eyes, it really is, well, at least when dealing with text. Since the area of the screen is the same, it just has less pixels covering it, each pixel is BIGGER, thus making everything bigger and a tad less sharp, however it is by far not a blur of colors. I like WXGA because its easy to look at, and easy to work with text because it is bigger and easier to find what you are looking for. However, the downside is that you can only have so much stuff on the screen at any given time and have it be visable. For instance WXGA is wide enough so you can have a word document open, and have your AOL buddy list right next to it so you can see as your buddies get on and off as you type your paper. However, if say you want 2 word documents side by side, space can get a little bit tough.
WSXGA on teh other hand makes thinks look a bit sharper (images and movies) but it also makes text smaller, so you might yourself reaching for the Ctrl + (plus) all the time to make things bigger-looking. I am not saying its a bad thing, it just depends on how you like it. Granted since it has more pixels, your battery life will be a bit shorter than on a WXGA screen.
my best advice is go to Best Buy or something and look at both types, see what you feel more comfortable on
