Thanks Ernst,
I feel like a rock star with my name on a thread

Glad the reviews are being well received. I still think there's some work to be done on the 7900 review. Right now i'm still in the initial impressions stage. I'll be testing the printer with a beta version of a new RIP, which should help to inform my feelings about the Spectroproofer. Also I'm interest to see how the version we have differs from the final shipping version, or if we'll see firmware changes similar to those from HP.
In regards to the APS comments. Yes the APS wont offer much if your only going to work with HP paper. On 3rd party paper, some work better than others. The APS allows for larger charts, but that's not going to make a paper with compatibility issues look any better. If you have a RIP and want to make CMYK profile, this is the place for the APS. Yes the APS is an accesory, although it is included with the PS version of the printer.
