We are just getting ready to sell our old house after moving a year ago and remodeling. (Don't ask why it took so long.)
On the advice of our real estate agent, we installed a cork floor in the kitchen. She had one growing up in Denmark, and really liked the warmth and cushioning it provides. However, her main concern was to create value and increase the desirability of the house, so I don't feel like we did this to bring back her childhood.
This was my first Festool project, using the TS-55 and MFT 1080. I did install snap-together panels. The pattern on them looks like small cork 'bricks' of random lengths, almost, but not 100%, hiding any seams. I was very happy with the results -- it looks fantastic, and the tools were perfect for the job. There was no recommendation to seal the seams, and I did not. I can't comment on long-term durability, but it looks and feels great. As is often the case, the house now has the kitchen we would have liked 10 years ago.
I'd do it again, and would probably consider it in our new house when it comes time to replace the vinyl.
