Rather than the negatives, I think it's closer to asking the photographer for just the film--before any development is done. With a negative, you've already done some processing with regards to the timing of the film development (push/pull) that you can arguably accomplish in Lightroom/Aperture/etc. when processing the RAW file.
Dual booting Ubuntu 13.04 on the Samsung ARM Chromebook with XFCE as my window manager. So far it's been working well as a machine to get work done when I'm away from the desktop. I rarely boot into the ChromeOS side, though.
