Adobe has come a long way since the days of Type 1 and PDF. Most people don't even remember that they created those formats. Now everything is about Photoshop and Illustrator the design programs they are most known for.
No program is perfect though and if you have been using the Adobe design suite for years I'm sure you would have thought of things you wished were included as standard. This begs the question... can anyone overthrow Adobe's design suite? or even one of the products in that suite? And what features do you think a rival would need to take down the multimillion dollar giant?
