I keep seeing so many threads here where many posters urge upgraders to spec-up the SSD capacity. Is it really necessary? First of all, Apple's storage upgrades are expensive as hell. Second, there are so many cloud-storage services out there to put your data offsite and it is not like WiFi is hard to come by in most places. Then, there are also NASes that you can put your data on. If I need to go overseas for work, I pack an extra external disk if necessary, but again, unless you're going to an area where wifi is lacking, its not that difficult to login to your NAS or cloud service to grab whatever documents you need. I myself am completely happy with a 512GB 2017 TB MacBook Pro.
