Hey.... I got an 8500 and absolutely love it. The UltraSharp UXGA is a little bit better. The SXGA is 1400x1050 pixels, vs. the UXGA which is 1600x1200. Both have 16.7 million colors, yadda, yadda, yadda. Also the UXGA can be seen from a much wider viewing angle. If you're going to watch DVD's on it a lot, I would go for the UXGA, it will give you really good resolution.
Here is a link:
Right in the middle of the page by UXGA, click "Learn more." Then you can compare them. Hope this helps....
