My IDE provides 98% of the pixels on my screen and provides 90% of the overall experience. That’s why it gets all the attention. If the OS is able to show my IDE on one screen and a web browser and UNIXy terminal on the other, it’s working.
So you don't use the built-in Terminal? What about Finder, Safari, Mail, Spotlight, System Settings, etc? If someone doesn't care about how they look, they should use all the built-in stuff right?
