Xcode has a Touch Bar simulator and it actually works system-wide-- so if you're developing for the thing and need to get a feel for how Apple's using it, you can.
You do have to update macOS, though-- it's not included in the 10.12.1 build released a few days ago. The build you'll need is linked on Apple's developer site: https://developer.apple.com/macos/touch-bar/
I'm having a little trouble figuring out if this comment was sarcastic or not. Regardless, I think it illustrates pretty clearly why a lot of us are really uninterested in the TouchBar.
Hopefully the next XCode build will include a TouchBar simulator so there's no need for me to get a new MBP in order to work on this.
