Which should I get? SXGA OR UXGA?

Your best bet is to go to a store with SXGA and UXGA laptops and see how they are. In the end it's personal preference.

What are the pros and cons of each type? Thanks

Well as with any LCD, you need to run them at their native resolution to look their best.
The UXGA is 1600 X 1200 to look it's best. That makes everything on the screen crisp, yet really small. You can then turn up the text size and DPI for a more normal view. Some things will still remain small though such as pictures/picture text. It's up to you if that's how you like to view it. Having the 1600 X 1200 option can be usefull in some games and programs.
The SXGA+ native resolution is 1400 X 1050 which is closer to what the average person runs. The displayed items will appear larger naturally, but you won't have the option to go to a higher resolution.

In the review I posted in the review section here, I have some talk about the SXGA screen on the 8886 as it compares to the SXGA+ screen on my own lappy... It's not a comparison involving UXGA, but you might want to read it to get some more info if you'd like. Just thought I'd let ya know :-) Good luck with your decision!

One thing that I think is an important consideration between SXGA and UXGA is the difference if you have a dead/stuck pixel. As the 5660 was my first laptop, I was not aware of this issue, and was a little worried about it based on some people who had had new laptops arrive with dead pixels. Having recieved mine, I have located 2 stuck pixels, one dark blue, top center of screen, one light blue, top left corner. They were discovered after a close (i mean close, lol) inspection as in UXGA it is impossible for me to see them from beyond about 4 inches away from the screen. For SXGA+ I bet it wouldn't be much of a problem either. But I have heard from some people on here with the 8886 having complained about a stuck white pixel being an annoyance. Additionally, the program I will be running on it for work, AutoCAD, I have heard is just awesome in UXGA. Other than that, it really is a personal preference, but rest assured, after making the adjustments for the small text, and with young eyes, I am highly pleased having gone with UXGA. Good luck, I think you will be pleased with your new computer either way

PS. Shameless unsolicited plug for PCTorque. I ordered my computer last monday night, well after business hours. I got lots of e-mail correspondence, the machine shipped on TUESDAY!!??? and by friday afternoon, I was sitting down with the brand new machine, which has worked perfectly almost nonstop for the last 3 days, through all the technical stuff of setting up a new computer. No problems, no issues. Just quick (4 frickin days!!!!!) and easy. I think it is important to note that a company that has good service when problems arrise is good, but a company that reduces the amount of problems is even better. I will be sure to hop on reseller ratings, and I urge any who havent yet to do so as well, as it will help this community to grow and prosper.

sorry about the 'Im with stupid' thing. I meant it to point to me, but I forgot there were other posts above mine. This was not inteded for any of you, I got nothin but love for all the people on here.
