Airtable - The ease of a spreadsheet with the power of a database

Looks we finally have a worthy successor to the Bento database on iOS. There even seems to be an upgrade pathe for Bento files. Unfortunately, no iPad app yet.

Looking forward to trying this out on iOS. I've noticed that tools like these (databases for the masses) often fall in an awkward area straddling simple/scalable and complex/powerful, and typically land in a place that leaves "power users" feeling trapped. Is this a tool that most tech-savvy users will quickly outgrow, or does it provide legitimate value at all levels? Asked another way, what types of things are your employees (who have intimate knowledge of its potential) actually using it for?
