I have had my 2012 MacBook Pro 15" with Retina Display since August 2012, and I couldn't be happier! I edit with Final Cut Pro X, create music with GarageBand, use Photoshop, and convert videos, and my MacBook handles it like a champ. It seems that the SSD is what makes a major difference. El Capitan also helped make things even snappier! Based on how amazingly it's working, it'll be years before I'll need a replacement. How does this compare to your experience? Is your Mac running well?
