I've gone through a 30 day trial of Aperture and LR and decided to go with Aperture. I've got the pop up window which tells you to "click Buy to purchase a serial number or order a boxed copy". That takes you to a page where you can buy a boxed copy for £173.00 or an Activation Key for £169. No mention of the App Store version at £44.99! No thanks! Unless I've missed something, it looks as though I'll have to ditch what I've done in the trial and start again with Aperture from the App Store. Thank goodness I didn't do too many photos! I suppose it's too much to hope for that I'll download it from the App Store and it'll recognise it's there already and I can carry on from where I left off?
