While mostly obviously identify as a software engineer publicly, the majority of my time is not spent writing code always.
Because of this, the iPad Pro is my computer of choice for pleasurable computing — creative work, consumption, writing, email, and even getting things done.
I keep everything (Documents, Desktop, repos directory, Sublime Text configuration, etc) in iCloud Drive storage. For those who don't know, the location of this sacred directory is as follows:
cd '~/Library/Mobile Documents/com~apple~CloudDocs'
Which, I always create a symlink to in my home directory:
ln -s '~/Library/Mobile Documents/com~apple~CloudDocs' ~/iCloud
I still use Dropbox for a few things — specifically, my iTunes library, Game ROMs, and recorded video files (which I'm slowly migrating to Photo Library).
As a photographer, I keep all my edited photos (e.g. published JPEGs) in iCloud Photo Library, carefully organized, and they are automatically synced across all devices. This setup has worked great for me for years.
All "works in progress" are stored in Adobe Lightroom CC, which is accessible from any device, including my Windows PC, and is very pleasurable to work with. On the iPad Pro, moving sliders is lightning fast, with instant response time on the image preview — far faster than it is on any Mac. Syncing is also instant between the Mac and the iPad. I've seen no conflicts thus–far while using the software on multiple machines at the same time either.
