It is interesting to see you say about your dissapointment with XVR-1000
performance. I got to play with an XVR-500 not that long ago and was
surprised at just how spritely it was relative to the XVR-1000.
Considering the amount of money it cost us when it was launched, the
performance has been very dissapointing. The Sun document referenced by
the other poster is interesting in that it shows a significant
performance deficit from what i would have expected previously.
