Hello to all, I am a former Mac Addict (I used to love Macs) then along came OS X... an ok OS, but frankly the learning curve taught me UNIX, which in turn led me to LINUX, well the rest is history, I made it my mission to replace everything I do on a mac in linux. I work for a publishing comapny and I am almost fully switched over, for a while I used mandrake on a PPC, but it is buggy on a mac, so I loaded Knoppix onto an old (really old) i686 and boom everything I need.
Here is a list of what is needed.
Photoshop = The Gimp/Kooka
Illustrator = Sketch/Karbon14/Scribus
Indesign/Quark= Scribus

And that's it... Scribus lets me create a PDF which I can send off to the printers and it's ready to go.

My biggest complaints, fonts, but I need to learn how to add fonts, I have about 3000 mac postscript and truetype fonts, I am sure there is a way to do it, I just need to learn. Also Barcode creation, there are several options, again I need to learn the installs etc. So if you really want to do it... linux more than measures up.
now if Knoppix ever ported to a PPC, I could use all these old Macs I have.
