See I find the opposite is true for me. I don't have much experience with OS X but between ubuntu and Windows 7 I _much_ prefer Win7. I just can't stand how much screen space is eaten up by useless padding, menu bars, sidebars and panels, not to mention the overly large fonts. I realize that everything is customizable, but I don't have the patience. Windows 7 also seems faster and more responsive to me but responsiveness is largely subjective and situational.
I'd appreciate it if you did. I primarily use emacs on Windows, so that aspect is not a problem, and I weeding through all of your cruft might be fun :)
To each their own I guess.
