Mark Pilgrim commenting on his own post about his switch to Linux:

Yes, as I noted a few weeks ago, I bought the Canon PowerShot SD450. When I plugged the camera into my shiny new install, Ubuntu immediately recognized it and offered to import the photos, which I did, and it worked. I believe this is the work of libgphoto2, which is one of those amazing little libraries that does one incredibly useful thing incredibly well and just keeps getting better for free. Someone out there *really* cares about interfacing with digital cameras, in much the same way that I *really* care about parsing RSS and Atom feeds.

Thanks Mark, you made my day with this user testimonial. I know switching is not easy, and I'm really happy that the libgphoto developers made your life easy for that part.
