My indecisiveness has gone on for 2 years! 2 years ago when I graduated I had a Dell XPS gaming system, maxed out, with a Samsung 24" 1680 x 1050 monitor. I used it as a bit of a render farm - basically the brute power made up for my lack of ability at rendering. The reason for the Dell was Power Vs Cost compared to a mac, plus my life was all in the same place, so a desktop was ok. Since then I've got into employment and the technicians do the rendering and I do calcs, project programming etc - so less "brute force" in terms of power for my day job and I work in varied locations. As I've always been on the Mac side (iMac G3, eMac, G4 Tower, iBook) I decided to treat myself to a shiny new MBP 13" 2011 model, but sold it within 6 months due to the Intel 3000 graphics and the upcoming refresh (2012 models). I lost patience and just got a Mac mini with AMD graphics and a 1080p monitor but hated the lack of portability, so bought a MBP 2012 13" model with upgraded RAM and better Intel 4000 graphics, but I'm finding it limited in terms of screen resolution. In my spare time I've set up a small print venture, do some digital graphics work, along with iBooks publishing and I'm looking at 3D printing, the screen real estate feels too cramped, I want more on the screen but I feel I'm limited by the low resolution. Additionally we've started to travel on weekends and I take my DSLR and my iPad Mini which for me is the perfect combination, so I wouldn't be necessary to travel with the machine everywhere, just have some portability. So I've been looking at: 2012 Macbook Airs 13" - will the extra resolution be enough vs the power loss. 2012 retina MBP's - 13" provide more estate or just more detail? 15" too expensive or my ideal machine I need to splurge the cash on?! 2010 MBP 17's - Too old? 2011 MBP 15's - Good compromise? I would settle for an older machine on a cost basis but I really want a machine that will last 3/4 years which is why I'm leaning towards a new machine - plus USB 3 and thunderbolt. In terms of budget I want my needs to take priority as I'll only end up changing again. Any help much appreciated.
