I would think that most of the real knowledgebase for this is going to be at AVS.
This article didn't hit home for me at all. I bought TWO of the Dune players years ago. This was before getting a reliable player was much of a thing, and they were pretty expensive. Set up some RAIDs in my home and ripped my entire BD collection. No downloads, all true 1:1 BD rips. They were okay. That was kind of it, at best, they were okay. Dune did allow for some plugins for a movie wall, which I went with, and worked on, but it was a labor of enjoyment, which soon turned into just being labor. I mean, it was cool to get the movie wall, but it wasn't automatic, and it wasn't built in.
Zappiti was the promise of making movie walls fully automatic, but it came at a price, which I didn't buy into. I could live without it and just browse to my recent downloads if I wanted to...
Then came Plex. I had tried XBMC (Kodi) a few years before and was really bugged by how much hand holding it needed to operate properly. But a few years had passed and people were talking about Plex as a good option. It wouldn't read my native BD rips, but I had converted some to MP4 files for my iPad to watch on the go, so I had some files it could index. I also owned a Roku so I could try out a player. 30 minutes later and it was all setup and ready to go. No hand holding, no fuss. Just installing and running through some steps. A few days later I had added some content and it seemed to be nearly flawless for my needs. I got the one month pass which I paid for... and a month later, I bought the lifetime pass.
I removed my Dune players from my equipment rack a couple of years ago and nobody in my house has missed them in the least. Converted all my BD.iso files to .mkv files and haven't looked back. I love that Plex offers a lifetime pass. I hope they stick around that long as well! I love that Plex has grown so popular that it is showing up as a quick shortcut button on some remotes. I love that it's on basically every major platform and television out there.
I feel bad for Zappiti owners, but I'm glad they have options.
I have no idea what Zappiti would offer people these days which is a big improvement on what Plex can deliver today. Or, what Plex will offer in a few years as things continue to progress with their software.
