Couldn't do without it. I hope that it becomes so accessible that everyone can run it in the future, but it's not hard to dip your toes in now. If you don't have any dedicated HW you can run 24/7, you can get a cheap RPi. If you're ok splurging a hundred, try something like a zimaboard.
The latter has the advantage of coming with an app store, which is docker wrapped in a click-to-play coat. I have a couple zimas but I use compose, so haven't tried it, but it should be very friendly.
