I'm shopping around for a MacBook Pro. I'm currently using a 2009 MBP with 8GB of RAM. Since that machine has lasted me so long, I'm looking for a new MBP that will last me for the new several years. I do some video editing, audio editing, and run Parallels for applications that don't run natively on the Mac. I prefer the portability of the 13 inch over the 15 inch. I'm most likely going to get 16GB of RAM (I used to buy the base model and upgrade the RAM when necessary...but since that's no longer an option, I want to have the most RAM available from the get go). No one here has a crystal ball, but it's it likely that the mid 2015 13 inch MBPs would handle everything I mentioned with ease for the next few years? Would taking a step up and going for a 15 inch (and therefore, a quad core processor) be overkill?
