Just a guess, but because a big part of the simple approach meant leaving things like DNS and IP Addresses out of the path to making something? You have to use their build, which I'm guessing as some mDNS stuff baked in (yes, it does - http://coder.local) with a pre-arranged name, and without Bonjour installed, a Windows box wouldn't find it.
Exactly. So if you didn't install the Apple crap, you would just have to track down the IP of the RPi somehow and use that instead of the fancy "coder.local" hostname
