i don't have it. i'm trying to understand the marketing aspect. i can see the potential in having a tool that allows you to design and then creates the templates for you. once you have that what do you need the upgrades for? you won't use their fabric, will you? so colors are all you need. right? there are free patterns all over the internet, so do they give you something different? how much does it cost to upgrade? does that mean re-buying the whole thing or retrofitting what you already have? when you upgrade, do you keep what you already have and add on? in other word, why is the original purchase no longer satisfactory, especially if it may not be computer friendly with your computer?
it seems to me that they have designed it with built-in obsolescence.
