It's not super complicated, but you are unlikely to figure it out without a couple internet searches. You have to setup the router, which isn't that difficult, and then wait to get connections. the torrent client is built into the router software, but you have to find the right I2P sites to get torrents because, as far as I know, only torrents inside the I2P network are usable. Each of these is pretty minor on its own, but adds up to a difficult experience for the average, non-enthusiast computer user.
I have been using tribler for a few years. It works well, abeit a bit slower than a plain torrent program, but still very reasonable.
I see a lot of people talking about using I2P for torrents but, as far as I know, I2P cannot use torrents from outside the I2P network. In addition to this, there is a non-trivial setup and confusing interface that people need to learn, whereas Tribler acts like any other torrent program, just with onion style routing. I really like I2P, but there's still more work to be done to attract more people and make it a truly viable alternative for most torrent needs.
Went to the beach yesterday. Saw a toddler eating sand. No adult nearby. Checked around and found the dad. Told him his kid was munching on sand. He said "Yeah, thats sort of his thing". Thought I was being trolled until he did nothing about it and continued on with his day unaffected.
