As an Aperture user since its initial release, I have to say that this latest version has some pretty significant improvements and new features. Everything from import, labeling, file handling, accessing multiple Libraries without exiting and restarting, etc., are all great to see. The image handling features are also most welcomed, especially things like the brushes, CA removal, etc. The outputs are also improved, and there is a wider selection of vendors for quality books. (I have been making books for my clients for several years, and they love them. The new additions/options, including a 13x10 book should be a big hit.) This new update includes import of HD video files with some ability to adjust/size clips, and then import them into slideshows, etc. While not a full NLE, like Final Cut Pro, it does look to be useful for folks starting out in video, maybe going on to bigger/better handling later.
As for the camera listing for files....there are some mistakes in their listing, so do not despair yet. For example, they have listed the Canon 1DsMkIV, which does not yet exist, but failed to list the 1DMkIV, which is already out. Besides, the camera/file handling is still controlled by the OS, not the app, so updates come along all the time. Would be nice to see a complete and ACCURATE list, however ;-)
