(I know this question gets asked fairly often, but since the tools constantly change, I thought it would be appropriate to ask again.) I have a friend who wants to start developing some web stuff, but doesn't want to fork out the huge initial investment in the standard Adobe tools (in this case, Dreamweaver, Illustrator, and Photoshop). Can you comment on the current state of open source or low-cost tools that come close to these for an aspiring developer? I am overly indoctrinated in the Adobe way, but my first guess would be to recommend Gimp for bitmaps, Seamonkey or OpenOffice as (not really good) html development (and no site management tools?), and... I dunno what for line art. What can you offer that may be better/easier/more robust?
