I think that the general consensus is that Open Source software apps such as Inkscape, GIMP and Blender will never replace their industry standard counterparts because there’s nothing wrong with these products in the first place. FOSS packages such as Open Office and Firefox (and to a lesser extent Ubuntu) have only really gained popularity because their counterparts are kinda rubbish. Neither Microsoft Office or Internet Exploder are as standards compliant as their FOSS counterparts and, in relation to Microsoft Office, you can save a lot of money by using Open Office that, whilst it has its flaws, offers very similar functionality to Microsoft’s product at zero percent of the cost! Brilliant!
When I start planning workshops soon, I’m still going to plan them assuming that they don’t have the necessary software (not all schools have Photoshop-like software) so will offer the use of FOSS packages. I think education is where Open Source will find its place in terms of design. What do you all think?
