Man am I having a hard time deciding.
The display wars comparison really just show that its an aspect ratio change and not really a "what you can see" change.
But maybe wider is better than taller...hmmm
For gaming purposes, Ive used a 30" for years and I really like the 34" 21:9 screen for gaming.
For general messing around, the width of the the 34" is very noticeable whereas I dont notice I am missing the height or 160 pixels at all!
Coming from many different monitors including a 30", this new 34" is by far my favorite!
