Hi all, I'm shopping around for a suitable 15" rMBP. So far I'm set on going for the base model - I just couldn't justify the steep asking price for the .3GHz processor difference and the 512GB SSD. I can live with a few seconds' slower difference in the processing speed of the 2.3 and as for the SSD capacity, I'm living on a 120GB hard drive that's not close to full. I'll be glad with the extra breathing room. Where I get stuck on my decision, is the RAM. This wouldn't be such a big issue if the RAM was user-serviceable: I'm more than aware of Apple's premium pricing on their hardware upgrades and would not hesitate going for a third-party manufacturer. But since the RAM in the Retina is soldered to the logic board, I need to make my decision at purchase. Right now, 8GB is more than enough for my needs, but I'm also thinking 5 years from now (which is how long I think I'll have this laptop before upgrading). Will it be enough then? I'm not a power user. And I'm not an extreme multi-tasker by any measure. At the most, I'll have Safari, Mail, Pages (or equivalent), Adobe Reader and Photoshop open. But my usage pattern may change in the coming years to accommodate Final Cut Pro for video editing and Parallels. I doubt I'll be running PS, FCP and Parallels simultaneously. But you never know. I'm leaning towards the 16GB, since I opened Task Manager on my Windows 7 desktop as I conducted my usual workload - Google Chrome and Adobe Photoshop CS5. Just those two. When I used the photomerge tool to stitch a Brenizer-method panorama (for that crazy DOF) the RAM usage jumped to 6GB out of 8GB! And it was just those two programs open. However, I don't know how comparable the Windows usage is to Mac OS X. It could be different. Your input will be greatly appreciated Anything to help me come to a decision soon. Thanks in advance!
