Everybody has their personal preferences- I'm glad if you're happy with your set-up. The whole purpose of my comparison test, which I'll continue for a few more days, is to find the one that I'll be happiest with over time. Just a couple points of clarification:
A Sonos ZP80, the unit comparable to the SB3, sells for $349, exactly the same as a wireless SB3. They're both very compact, have similar connectivity options, and sound about the same. Differences:
* If used alone (with no other Sonos units running in the house), the Sonos does need a wired connection to your network. This can either be a direct connection to your router or through a a wireless access point. With more than one Sonos unit, only one needs to be wired. SB3 & Transporter can connect wirelessly to your network out of the box.
* If you add the remote to Sonos, that does indeed more than double the cost (it's $399 purchased separately). And in fairness, you'll want the remote because it's pretty cool. It makes navigation, playlist creation, jumping around between music services and other sources, as well as managing the whole system, really easy and intuitive. Beyond other ease-of-use comparisons, the most fundamental difference with the remotes is that you interact with Slim Devices equipment at the units themselves, reading their front displays as you navigate through menus, while you interact with the Sonos devices on the remote itself. The player can be completely out of sight.
* You're right about using universal remotes. SB3 & Transporter can be operated from any programmable remote (just like the native remote, you navigate through the units' text displays). The Sonos can only use its own remote, because it's designed to bring its interface to you. No universal could replicate its functions and hi-res display. (It would be like trying to operate your iPod from a universal remote, without being able to see the iPod's display.) If you really hate having more than one remote lying around, and can't/won't use a computer to control your device, go with one of the Slim Devices products.
* Alternately, both can be operated via a computer interface. With Slim Server, you log onto the network share from which it runs via a web browser. If that's over a network (on another computer or NAS), it's kind of clunky, much like exploring files over a network. Which is pretty much what you're doing. Sonos uses an application, called the Sonos Desktop Controller, whose interface looks a lot like the remote display. I really don't understand why (because it also has to operate over my network), but it's much faster. And again, I just find its layout more intuitive, informative, and responsive. The earlier iPod reference is apt: lots of devices do the same thing as an iPod, but so far, none do it quite as elegantly, hence the gazillions of iPods sold in the last few years. (Ironically, I'm not an iPod user, because I prefer FLAC encoding, which is doesn't support.)
With that, SB3 has advantage over Sonos because Sonos is still closed interface (as far as I know, let me know if that changed).
I'm not sure what you mean by closed interface....but both are accessible from every computer in my house.
I think both companies make great products, and they share the biggest advantage of all- making all your music readily accessible. No more not listening to something just because I don't want to go to the trouble of hunting for the CD. This has been a real revelation for me, and I'm happily re-discovering my music collection everyday. Each has its pros and cons, and I share my descriptions and opinions in case they might be helpful to people trying to decide which might be best for them.
