Screen for 6000

Me personally, the UXGA is way to small for me to see clearly (Older eyes you know).  I prefer the SXGA+ screen size.

It's really hard to tell you what is good for you.  If there is a Dell kiosk in your area, then I would suggest going there and look at the different resolutions.  Then you can decide for yourself.

 

Personally I like my WXGA screen.

Is there any appreciable difference in getting an ultrasharp?

I have the WXGA for my 6000's (I have 2). I love them just the way they are. I went from UXGA 1600x1200 on my I8200 and I am much happier with the lower res screen. It is much easier on the eyes. The only difference in Ultrasharp vs. Non is the viewing angle on Ultrasharp is much greater. They are supposedly brighter too, but my Ultrasharp I used to have on my 8200 was dimmer than the new 6000 screens I have now. Just my 2 cents.
