Budget: $3,000 +/- a few hundred dollars. Use: Editing/processing GoPro videos (4K), DSLR photography, moving large files between computers and Firewire 800 hard drives, note-taking, homework, paper drafting, research. Looking for a system as a student to take on-the-go for note-taking, research, homework completion, some multi-media use, emails and client/work communication, but still can handle whatever I may throw at it within reason. But I also need a base PC/MAC for home use that can handle editing/processing GoPro video's, some DSLR photography and can still be usable with an adapter for FireWire 800 drives that have a lot of old university documents, GoPro files and my old photography backed up to. I was considering a 21.5' 4K iMac and a base MacBook retina. It would be slightly above my budget, but I felt it could handle my needs better than my 2010 MacBook Pro could currently (Which the logic board, hard drive connector and airport utility tool are all failing).
