"He who marches out of step hears another drum." ~ Ken Kesey
The screen angle/dot shape/frequency options in the print separation dialog box are gone in Photoshop CS5. If you get the Creative Suite you can place your files in Illustrator and output through that print dialog box and get the options except for dot shape, unless you print as postscript or Adobe PDF and use Adobe PDF as your printer. Printing to a postscript laser printer doesn't let me choose the dot shape. I think the same options are available in InDesign. I've still got CS3 installed and can always go back to that.
I've never really thought of Photoshop as being good for output. Always Illy for that.In CS3 we lost the ability to place Photoshop PSD files with separable spot channels. It apparently was a workaround for a "bug" for the offset guys.Pick one and stick with it, you likely don't need any of the new features (although gradienttransparency is pretty nice) and once you get accustomed to the layout it's hard to make the jumpto another.
I guess adobe want people to spend more money

When I started design school, I only new a little about photoshop and not much about illy. As time went on, I learned more about both and found that I didn't really like photoshop for anything outside of photography. I am really baffled as to how photoshop has become an illustration and design program for some people. Ok, I can see its use for illustration, but I still think that illustrator is a better tool for that. Indesign is the real deal for layout, even if it is one page, it kicks illy's butt all over the place.
