Thanks! Very interesting.
I think one thing that people have to keep in mind is that the 'inaccuracy' we're dealing with here is likely pretty low by most people's standards.
If you're paying someone to calibrate your display then by all means you'd hope they don't show up with a only a $150 Display 2 or a even only a $400 Chroma 5. You'd *hope* they'd have at least an Eye One Pro ($700) or something better.
Now, when buying for yourself, it becomes a question of what's worth it to the individual: Is it worth paying 3-4 times the price (or more) to get what in most cases will likely only be a few percentage points of more 'accuracy'? Only the person holding the purse strings can answer that. Of course, the better metters do other things better too like stay accurate longer and have the ability to NIST certified ... and so on).
Since I'm somewhat involved (in a sideways manner) in this industry, I'd be very happy to see everyone buy an Eye One Pro instead of a Display 2 !
