Hello all this is my first post. I am in the market for a new computer to utilize Logic Pro X, Abelton light, Pro tools, etc. I am currently using a MBP but I need something with more speed/memory that is a dedicated studio machine (that will probably see other light use on web browsing, solitaire, and what not). There have been a million threads on the 21.5 vs. the 27 but my main thing is would the extra screen real-estate be worth sacrificing the SDD I could afford on a 21.5 model? Ive looked at my finances and that is what it comes down too. I can either get a fully maxed out 21.5 or an i7 27inch w/ 16gb of ram but keeping the HDD. Basically when using heavy applications like logic or pro tools will I miss the SDD or the screen real-estate more. My MBP has the SDD so would an imac with an HDD be slower than my MBP? My 15 retina is also definitely a bear to work on for long production and recording sessions because of screen size. I love my MBP and I plan on keeping it for many years and it will serve as an idea machine as well as its main use which is for school. So whats my best option? please and thankyou!
