I'm noticing a trend (anecdotally) towards hosted eCommerce solutions (eg. Shopify, BigCommerce, Volusion, etc.). And I can see the advantages of the hosted approach over traditional (self-hosted or CMS add-on, eg. Magento, osCommerce, LiteCommerce) and how they fulfil the requirements for many online shops today.

I'm curious to find out what everyone is really up to today? (Please vote on the poll.) What reasons motivated you to select the eCommerce solution that you did?
