oldschool: Lol, better yet, Paint shop pro. The funny thing is it would still cost over $150 @ 90% off. I think this is a dangerous trend, let the software companies continue to distribute the old fashioned way, Boxes. Digital distribution for this type of media is a really bad idea. I think Steam should just focus on Games, not actual software.
"Proper programms" are also a whole different can of worms legally. I don't think the Valve legal department really thought this through. Or was ignored, as usual.
But the "boxes" distribution will run out eventually. Generally, software providers no longer want you to buy licenses, but "service suits". The recent ECJ ruling has accelerated this trend immensely...
Elenarie: No, no, no, no. What purpose does a box serve to a software product?
