The fact that Aperture is still on sale despite the fact that they have publicly announced that they are getting rid of it is a surprisingly scummy move from Apple. I mean will they refund you if you are dumb enough to buy it the day before they get rid of it? Not only should it be gone now, they should be offering Lightroom in its place. From MacRumors:
“Shortly after last week’s deployment of OS X 10.10.3 to developers, Apple updated its official Aperture page on its website, adding a notice stating that Aperture will be removed from the Mac App Store when the Photos for OS X app launches.
The same notice can also be found in the app’s Mac App Store description, as noted by MacGeneration [Google Translate]. Once removed from the Mac App Store, it will no longer be possible for new users to obtain the Aperture software, but those who have previously purchased Aperture will continue to be able to download it from the “Purchases” tab. ”
