I've tried to adopt the alternative bash systems on Windows, and they are nowhere close to terminal options on OS X (or Linux!). It still boggles my mind why we have to stay within the limits of the cmd.exe UI, with the lack of window resizing, easy copy/paste, and proper font rendering. Then, on top of that, Windows will never have a proper unix-like filesystem. I just can't go back to that.
The only thing windows has going for it when it comes to development is performance. My windows desktop screams compared to my mac, but is relegated to gaming.
