I got my Zonbu box in August, 2007 and I have been using the system a lot. Here you find my impressions that I update from time to time.
This review only covers the first Zonbu, the "mini".
The Zonbu team changed their pricing model several times ... so this review might contain pricing or subscription modells, that do not exist any more!
The big problem with having your mp3 files in the online storage is that it takes Zonbu time to download them before the music starts playing. To wait 5 or 10 seconds till a pop song starts might be tolerable, but it really gets annoying with larger files when listening to classical music. (Each set of the Brahms symphony, to which I am just listening, is about 20 MB in size. This leads to quite a break between sets ....)
And even in pop music are many albums where the different tracks blend in on another ... so the break between tracks is not acceptable (I had this experience the other day with: Genesis - The lamb lies down on broadway).
We run the Zonbu on a 6 MBit / sec DSL line. Most of the Zonbu target group will not have a faster access I suppose and so they will share similar waiting experiences.
So I practically stopped using Banshee for listening to music and now use the following setup:
All our mp3 files sit on a linux NAS device nslu2 that streams the music into our network using the protocoll mt-daapd . On the Zonbu box I installed the daapd client "Get it together" . (I had to become user root to install the client software on Zonbu.) So we now have immediate access to allmost 6000 songs ... but the Zonbu hosts only the client software, to play them and not the mp3 files.
In the meantime there even exists a flash based player for daapd called "FirePlay", that you can find on the daapd website. If you use that player, you do not have to install the daapd client sofware on your Zonbu.
Zonbu has enough power to run the java based music player in the background and to browse the web with Firefox at the same time.
Editing of digital photos: Zonbu comes with Gimp which can do a lot of things ... but I always forget how to do them. I stick to photoshop elements on my XP machine.
I use the Zonbu box to watch and show the pictures that I have in flickr ....
When it happened the first time, I was help within a day via email (but what would I have done if I had not had a working hazle free Windows XP machine around?).
The second time I solved the problem with a hard reset. Worked well and fast ... but after that the root privilege that I had installed, had been gone ....
Otherwise the stability is as good as on my Windows XP machine. In the meantime I use 7.1315. The problem seems to be solved.
I will not use the Zonbu to store personal documents on it and I will not use it for collecting and edition digital pictures (too slow, do not like gimp).
I will use it to listen to music, but as explained it will only be used as a player, while the mp3 files will be streamed from a different device in our network.
What I do not like is the 1:1 user / box relationship: you have to have your personal Zonbu and only your account can use this machine. So you need a Zonbu for Mom and one for Dad and one for every kid .... not very practical and not very "green" either. This is one more reason why I do not store data on the Zonbu. For me it is just a frontend device.
So in the future the upgrade plan for $ 3.95 would be sufficient for me. (This plan does not exist any more - for me the free "Zonbu free Open Source" modell would be perfect. It gives you free upgrades and updates AND even backups 250 MB of data remotely for you. For the way I use the Zonbu, this would be enough ...)
