I've been using Photoshop and Illustrator since a while with my 13 inch HP Notebook with 32 GB RAM.
Although I do not run other applications concurrently, Photoshop and Illustrator tend to crash after some time. I am planning to get a Mac Book Pro again but I am not sure if the fault lies on Adobe or on the hardware.
I need to travel with my notebook that is why I chose a 13 inch notebook. I do have a 13 inch Mac Book Pro from 2015 which I am not using anymore due to limited drive space. The question is that do Photoshop and Illustrator get displayed correctly in 13 inch Mac Book Pro. On my HP notebook I could not see the save or cancel buttons at the bottom hence making it difficult to edit design files when I do not have a bigger monitor.
