I'm surprised about the 266 MB of DICOM images, I've never had an MRI but my CT results are generally between 1-2GB (zipped) and I always assumed an MRI would have more data, guess I was wrong about that!
I don't touch my display on my MacBook and it's always yucky because of the finger oils on my keyboard, so the thought of having to use a special cloth to clean it always seemed like too much of a hassle for me compared to the glossy display. I did wonder if this improved ever since they added nano texture to the ipad pro, but sounds like fingerprints are still annoying.
For me it often still is.. at least when I'm working alone on something / no collaboration needed. Every time I try something else I revert back to this, although sometimes I do save the files, eventually.
Always reminds me of the time Apple introduces "Smart Shuffle" in iTunes in 2005 which "which lets the user change the “randomness” of shuffled songs".
