I've been running it on my laptop (chromebook pixel 2) for several months so far and it's great. I was waiting for this to be merged for a long time. Right now I have /home as a zpool than runs from an SDCard on my computer. The SD Card is a 64Gb card (the most expensive/fast I could find) and for my workload, it works just amazing: this setup leaves me with 64Gb (a bit less) for / and 64Gb for /home.

The ability to cd into snapshots is just great and a time saver. So far, nothing wrong/bad with this.
