Inkscape, this will start the ball rolling, it's a fast, constantly evolving Vector drawing application, that along with all the other Open Source Apps, will force Adobe into diversification, if not liquidation.
Why? because it is continuously being developed by a world full of designers, programmers, and media specialists, who all share a common ethos. That is to create cross platform tools for all to enjoy for FREE.
The traditional 'paid for' global software houses, who are answerable to shareholders, will become defunct. Be it web, be it film, be it music, be it digita,l open Source is the way forward.
I would like to open the debate, with Inkscape, no link just Google it.
