I bought Designer and Photo just a few months before 2.0 came out, and just before the window for free upgrade for existing customers begun.

I have to say it's more performant than Inkscape, clearly geared towards artists, but there are still stuff that are more easily done in Inkscape. These mostly relate to automation. To add insult to the injury there is NO plugin system for Designer. I think this is a huge oversight on Serif's part, people would be so happy to fill the gaps.
