I was struck by this comment, though:
"Using Shopify and Shopify POS together reveals our true
ambition: To be the first company in the world that fuses
all the distinct parts that are needed to run a complete
modern commerce business - all in one amazing product."
If anyone thinks they can run a complete business using only Shopify, they're sorely mistaken. It's only a shopping cart. If you want to actually ship items, you need to use one of their third-party apps or roll your own. Those apps are the reason that ecommerce with Shopify is still frustratingly difficult -- unnecessarily so.
