Best display I have ever experienced was oculus dk2 running a virtual desktop. The resolution wasn't particularly great but it was truly stunning to have this crazy curved display of your regular windows environment in front of you that is absolute massive (the size of it mitigated the resolution issues). It really gave a tremendous sense of scale and unlike many oculus activities, didn't make you want to vomit.
As a kicker, you'd turn around in your chair and you'd be basically suspended in space with a giant nebula to look at.
Apparently preorders start today, sometime - I'm in.
