Macbook Retina 15 1Tb with the highest end processor, which I use for video editing and Photoshop. Yes that machine is a speed demon, but honestly I found with 95% of the thing I do during the day this 12" Macbook is more than adequate. I can even do Photoshop with this 12" Macbook, I mean high end Photoshop with a hundred layers or so.
Other than the 3D interface(for those that know that) I am not inconvenienced here. Ditto for InDesign - although high end graphics does start to show a tiny lag there but nothing thats a deal breaker. And for fun, I did so some video editing on Premiere Pro, and it did take longer to render out(the SSD disk isnt as fast on this machine).
But it astonished me that it could. If I had to do minor editing on the road, in emergency cases, I can, although thats not the right Macbook for the job honestly.If you want to do any accounting, writing, document design, travel on airplanes, sit in a cafe and write all day long, then this is the laptop. The charger is very light to carry around as well. This can be your only laptop if you are not a graphics artist or editor.so I recommend this.
