I'm with you, and just moved to Google One myself (after subscribing for almost a decade). The value for dollar just isn't there for most use cases -- it's not worth paying 2x for a product missing key features like fulltext search and dealing with the constant, never ending upsell.

Dropbox seems to be hyper-focused on a market of graphics and other professionals where the speed to sync is their primary benefit. That seems like an unwise strategy to me, but I can see where those users would benefit from an esignature solution.
