First of all, I'm looking to purchase the computer anywhere from June-October - so I am in no rush at all, and 'hopefully' by that time, there would be an update to the system, because from what I'm hearing, the 15" is the recommended, even for hobbyists. Nevertheless I am curiously wanting to know what software will "just work" for my needs and what software will "defiantly work" for my needs. This is a laptop I am intending to use for both for School and travelling at years end, so I'm leaning on the 13" right now for portability, not to take up too much desk space, and have the BEST battery life - even one hour is important in my opinion. I've heard screen real-estate and horrid render time are what really push people over to the 15", I hope to hear otherwise. But I also need specifics on the capability for editing films, composing music, animating in Flash, and working lag-less Photoshop projects, to win over the 15". To be even more precise, I will explain the specific work loads I would do on the go: 1. Film Editing - Create YouTube format (2-10 minute) films, shooting on 1080p DSLR's, edit on Premiere Pro (though Final Cut Pro X is being advertised to be more efficient than Premiere - or is that just false? I may jump to FCP X later on if I hear more good feedback). Editing wise, the most effects I would use are Colour Correction + Grading & occasional small Image Resizing\Zooming fixes. I am rarely going to use After Effects, but simple point tracking can come into use sometimes. 2. Music Composition - I use Logic Pro X with half audio recordings, half digital instruments. if I were to make a complicated song, it would end up with 20 tracks at the most (which is honestly not much). I have seen proof that Logic Pro can even run on Macbook Air, so I don't think I will have any problems. I'm very much looking forward to having a laptop, so I will have the easy ability to plug into the TV and work on my setup there with a MIDI keyboard, rather on my powerful home computers desk - so this isn't at all an on the go type job. 3. Animation with Flash - I have not read or watched one bit of information regarding the rMBP's ability to run complicated Flash animations. I am hoping to hear about this, but in all honesty it doesn't seem like a likely situation where I would actually attempt to make an animation on the go (carrying around the Tablet and all...) 4. Photoshop - with Photoshop, I do things from drawing art with a tablet, making high resolution posters\artwork for other material I make, and most of all just making random picture edits for comedic purposes that I'd post on Social sites... Currently, the 512GB + 2.8 i7 (upgrade) + (maybe) 8GB RAM - looks like the current deal I would get. Hoping to get the best rendering times, but In real world terms, if this becomes the standard for the next model and a hypothetical 13" Quad Core is available (but way overpriced), this is the reason I am hoping to get feedback now + to get me excited and motivated for the wait while I save up.
