I am a professional video editor. I currently have iMac 27" mid 2011 with 20gb RAM, 1TB HDD 2.7GHz i5 - For editing. I also have MacBook Air 13.3" early 2014 with 4gb RAM, 128gb flash 1.4GHz i5 - For daily use and school. Maybe I should sell them both and buy a MacBook Pro, it will be better for editing since it's newer, it's i7, flash and I can edit on the go. Of course 15" are not enough, so I'll buy a screen too. The MacBook Pro will be used for editing and also for school because it's a laptop, but also strong. I don't care about 256gb vs. 1TB because I have 4tb external drive and 2tb portable external drive. So is it worth it? should I sell them to buy the newest MacBook Pro considering the benefits I said and also the new "Metal" for OS X? Thank you!
