I recently read an article that made me reflect on how often we are inclined (myself first) to use sophisticated web services and apps that propose to help us be more productive.
Sometimes alternative solutions are very easy and simple.
The blog post talks about how the author replaced note-taking apps by simply opening a new mailbox used only for this purpose.
This is certainly a creative solution that can actually be interesting for many people that don't need complicated features but only to keep track of their notes on the go.
