I understand. I used to dual-book my MacBooks because I like the keyboard and trackpad better. I stopped dual booting when Homebrew got good enough for installing lots of open source software on OS X. Also, I have enough Linux servers at hand, that I just use SSH, Emacs, etc. and can really do what I need on Linux from the command line.
Except for rarely booting my Windows 7 laptop, life is simpler using my Mac just with OS X and relying on Linux servers.
For development I'll take Ubuntu over messing around with macports, any day.
I only really use OSX for iTunes, as I don't want all the bloat that comes with it on my Windows installation.
