P2P is a very difficult option for any non-geek who wants to install ("just do it") the software.
I know many people who had absolutely no trouble downloading various things - including software - from all the P2P networks that flourished around 10 years ago. Not only torrents, but eMule, Kazaa, Limewire, etc.
They also happened to easily infect themselves with various malware by doing that, but I'd consider it more evidence of how "non-geek" they were.
(But all in all, despite the risks, I definitely prefer and miss that era of open filesharing compared to the closed proprietary walled gardens that have replaced it.)
