You (the user) doesn’t do this, X-Rite or OEM’s do it.
Irrelevant. Its new functionality for this product that didn’t exist in the past. Think about the possibility of updating or upgrading the matrices over the web, through software.
Exactly what I did. A colorimeter is a better suited and less expensive instrument of the goal is only to calibrate and profile a display. The Spectrophotometer if budget permits and one needs other tasks like building output profiles.
Edmund, I have an idea. Let them make their choice, you pay the additional cost over the Colorimeter even if they have no need for a Spectrophotometer.
The new Xrite colorimeter hardware looks carefully designed, and I give them an A+, for what it matters.
However, it is still a AFAIK colorimeter; the matrices will help Xrite a lot to match the device to specific displays, but I don't think they're going to help the consumer in the short run.
Also, I fully agree with you that this device is suitable for 90% of the calibration use cases out there, which nowadays are web design, prepress etc, but for LULA readers who happen to be photo enthusiasts *I* believe the generalist spectro tool is the more appropriate. I don't know about the US, but over here in France it's a free country and I'm still allowed to recommend one instrument over another, especially when I state that both are high quality devices, and both are made by the same company.
Anyway, we've looked at the new stuff some time ago, and I think we agreed we like the new hardware. It's going to be interesting to see what the pro and amateur photographers here think of the new instrument and its software when both get exposed to the nasty real world.
