"If you are a normal user, you'll just go with whatever is bundled with your operating system or bundled with applications you use (iCloud, one drive, google drive)."

This sounds right maybe five years ago, but seriously flawed in this age where people have multiple devices based on different kinds of OS. When you have multiple smartphone, tablet, laptop, and desktop computers, and replace / upgrade those devices every 6 months or so, you will find one of the best "features" of Evernote / Dropbox is that they are not Google/Microsoft/Apple. This OS / System independent nature of these products is especially important when you need to have access (also choose not to have access) your data from all sorts of devices.

Just imagine when you want to switch from an iPhone to an Android phone, at that time, you will wish your contacts and all other personal data is NOT integrated in the OS's platform.
