I have a long list of things I am hoping Apple will add to Aperture; lens correction is one of them.
Apple develops in private, Adobe does so in public so they give the appearance of being ahead (and some could reasonably argue that Adobe is currently ahead). It’s been more than three years since Aperture 3 was released. I am holding out hope that Apple has something really great in store.
Update: Scott Bourne says it best:
I think Lightroom 5 makes Aperture look more like an old man in need of a wheelchair. Shame on Apple for letting a great program languish— ScottBourne (@ScottBourne) April 16, 2013
