Rather than organizing your notes in a bare bones list format, Google's Keep works a lot like cork board covered in post-it notes.
Images, check lists, maps, sketches, and regular ol' text entries are kept on the static front page, rather than tucked away into folders, so you don't have to go digging for that entry you made last week. Just scroll down until you see the big headline on the appropriately color-coded tile.
While Keep doesn't offer the same formatting options for text, it does make the other features more prominent and easier to get to, so I'm more likely to open up Keep when I need to make a quick shopping list or want to draw a picture.
This view can be much more appealing on the eyes, but is clearly not ideal for long-winded musings or journal entries.
I suspect that fans of Pinterest will prefer this approach to notes, while Facebook fans might not.
