Regardless of the version number, Apple really needs to enhance Aperture. Reading other forums, many people are leaving for lightroom because of a lack of solid built-in features. Aperture needs better noise reduction, better sharpening, lens corrections, hdr, and more effects options.
I extended the use of the product by using the Google/NIK plugins. The plug-ins provide better noise reduction and sharpening. It also provided great tools for BW Conversion, HDR, about 200 other effects. I love the photo library management, but its photo editing shortcomes are really starting to show against the latest lightroom.
