I do not own an Apple computer now, but I'm planning on purchasing a new Macbook Pro (hopefully with Arrandale) when I return to America for Christmas. However, as of right now, I think I'm going to have to run Windows 7 or something on it - forever. Why? Because I have thousands of photographs that I've worked on in Microsoft's commendable 'Live Photo Gallery' software, which I've put dozens, if not hundreds of names and places tags in Adobe's XMP metadata format, which Live Gallery stores inside the files themselves, not into some XML or proprietary file buried in the OS. I can transfer the photos anywhere, use them anywhere, and not have to worry about the tags being stuck in the original OS or program. iPhoto looks nice, I've used it before, and I have no problems with it...but I can't lose 5 years of work and tags to switch to a product which isn't compatible with XMP. So, does anyone know of any good Mac software packages that will allow me to continue to catalog and organize my photo library with my existing tags? Even if it costs a lot, I'm willing to consider it!
