I'd just point out two things:
1) The software is actually free. A Color Checker Card is all you need.
2) There are some situations were this my be of interest
a) You camera doesn´t correspond to Adobe Standard profile
Your illumination is not like Illuminant A and Illuminant D50 on which Adobe Profiles are based. A good example may be flourescent illumination sometimes used for product photography or electronic flash. Neither have well behaved spectra but contains spikes. With a special profile based on your illumination you may get better results than with a standard profile.
I'd suggest that the Adobe DNG Profile editor may be more useful, because the profiles can be tweaked (for taste).
Thanks. So the question still remains: what (if any) use there is for this hundred dollar "must buy" product if the results are similar to the Adobe profiles?
