Ask HN: What are the reasons for switching to "hosted" e-commerce platforms?

Lately I've had a lot of store owners asking me for what would it take to migrate them to one of the hosted e-commerce platforms (Shopify, Volusion, Bigcommerce etc.). The thing is, that it makes very little sense to me. With self-hosted e-commerce you can pretty much do anything, while, for example, Shopify is sometimes so limiting, that even the most basic things require insane hacks. Hosted e-commerce is cool for starting your shop, but what's the appeal that already established stores see in it? Let's skip the basic answers - avoiding hosting, payment providers etc.
