Hello, I'm new to this forum and have come seeking advice on a purchasing a new MBP. I'm long past due to upgrade from my dinosaur 2003 PowerBook G4 12". I am a touring musician and occasional composer, and I used my trusty G4 for many years to run Logic 7, mostly for amateur/hobby home recording projects. It worked ok but never really had the processing power to handle projects once they got to a certain size. Too many tracks or plugins would overload the poor little guy, not surprisingly. I'd like to start being able to get a bit more serious about my home recording projects and have the ability to record and send tracks back and forth with producers in other locales, etc. So I plan to gradually start investing in some more serious gear. Nothing crazy, not planning a full service studio or anything, but would like to build a serviceable home recording setup with minimal gear. So, first thing's first, I'm ready to upgrade my Mac. I've done a fair amount of research, and from what I gather, to run larger projects on Logic smoothly requires lots of processor power and RAM. I know desktops are the best option for pure processing power, but being that I'm on the road all the time and I can't afford both its got to be a laptop so I can use it for my everyday stuff too. Aside from Logic (I plan to upgrade to Logic X) and Finale, and maybe eventually some other music production software like Pro Tools and Abelton, I don't really plan to run a lot of other power hungry apps, and if it weren't for wanting to do music production stuff I could probably get away with a MBA or less powerful 13" MBP. But I'd really like something I can grow into. So from the current line of MBP's, it seems the 15" quadcore is the way to go, both for screen size and processing power necessary for running Logic smoothly. The retina display doesn't seem necessary to me, and I would miss the built in superdrive, as I'm one of those people who still use optical drives, however the retina line seems to offer the most in the way of maximum processor speed and most importantly ram, 16GB vs only 8 on the non-retinas, and also flash storage is attractive for me since I travel a lot and it seems more durable than a serial hard drive. I found a Refurbished 15.4-inch MacBook Pro 2.6GHz Quad-core Intel i7 with Retina Display and 512gb flash storage on the Apple store for $2189, which seems like about as good a deal as I can find for those kinds of specs. I'm tempted to jump on it, but wondering if anyone has any insight or advice. I know the new Haswell MBP's are supposedly coming soon, and all the tech blogs say to wait for them, but I'm not sure if they will be worth the wait for my needs. Improved battery life would be great, but I don't anticipate often being in situations without power for hours at a time, as most of my use would be at home or in our touring vehicle which has a power inverter. If I knew for sure they'd be upgrading the specs of the cMBP's I'd be tempted to wait, but that seems unlikely, and it doesn't seem like the rMBP's will get a major jump in performance other than added battery life, and they'd presumably be more expensive than a good refurbished current rMBP. Thoughts? Should I pull the trigger or wait for the Haswells? Should I spend a few hundred more bucks and get the 2.7 or 2.8 GHz refurbished i7? From what I've read they're not that much faster for the extra $$, but I'd be curious to hear from anyone running music production suites on any of these machines. Would a non-retina quadcore with only 8gb of ram be a huge dropoff in performance? Thanks for any insight!
