I'm beginning to look around to upgrade a 2008 macbook pro and I was thinking of going with a table top computer. I thought the Mac Mini was the perfect choice until I learned that the 2014 models aren't upgradable. I believe in holding onto a computer as long as I can, so upgrading is key for me. I run Lightroom 5 and from time to time edit 300-500 photos per shoot. Currently storing 2014 RAW images on a portable drive. Current year RAW images are on the macbook with all JPG final images.
What mac system is suitable for a wanna-be pro photographer. I would consider another laptop if it where expandable.
