Herbert: "Photodesk ist not quite dead. I know a good programmer is looking into it planning to enhance and maintain it. But unfortunately it is quite a job and thus no dates given."
He'll have a hell of a lot of work to do then. Photodesk is way, way behind any vaguely modern bitmap editor. It needs to support RAW files and to have automated/intelligent functions added, such as Shadow/Highlights and lens distortion correction. It also needs it's own text renderer to produce crisp text for print and for the Web.
Failing this, no serious photographer will choose Photodesk.
