Decided to get, but have been putting off buying, Elements for my MacPro. Was about to pull trigger via App Store for $80 when I saw another poster mention Amazon having physical copies for less. They do have Adobe Photoshop Elements 10 for $65, but as I'm running Lion 10.7.4 I'm wondering if this would mean an immediate (or soon) update that I'd have to pay for. Can anyone answer this? Thanks in advance for any help!
