That's a valid point.There is something to be said about a larger internal SSD. If you have fast Wi-Fi access ALL THE TIME & everywhere you go, cloud storage is great. But if you Just like having all your junk local, go big.
It's important for me to have at least 300GB of local storage for my Devonthink databases and the apps I use. However, since I also have 2TB of iCloud storage, I should probably be fine with 512GB.
At the same time, I'm considering doing some photo work, which I currently do only on my iMac. In that case, having 1TB of storage would be greatly appreciated.
