What are the costs involved in switching from one design tool to another?

Guest: The cost is mostly time. You have to somehow embed a set of files in the new tool, get used to the new tool, and establish the overall system to work for you rather than against you. The switch and the creation of content took about a month to get to having everything in place. That's still much more valuable in the long term than having a scattering of files and diversions, which is actually the biggest nightmare.
