Professional Photoshop users already have existing hardware. This is trying to fill the gap that none (afaik) of the existing hardware offerings support Linux.

Also, if you really care, they say they'll ship a Linux Live CD with the device. So you boot your Windows machine with the live CD, take the readings with the device, save the color profile to a file on USB, reboot to Windows & import the profile. The generated profile itself is cross-platform. At least that's what they say :)
