My wife works at a small bridal shop. They are currently using HP stream 10 netbooks* to take orders while setting at a table with the bride/groom and family. The orders are stored on a desktop PC's hard drive where they are aggregated and sent to the vendors. I think that there are a lot of edge cases where you don't need a lot of processing power that netbooks excel at.

* I don't think they call the netbooks anymore, but effectively that is what I consider the HP stream devices. 32GB of non-upgradable solid state storage is all they have, and near half that is the OS install.
