EvernoteEvernote is another popular, free, online note-taking service. It offers effectively unlimited storage, albeit with a monthly upload cap (which is much larger for users willing to shell for one of the two fairly inexpensive tiers). The advantage of Evernote is its support for an incredibly diverse list of platforms, which includes native support on the BlackBerry 10 smartphone, third-party clients for Linux, and even scanners with the capability to scan straight into Evernote.Notebooks can be shared among multiple users – including those without a paid account – while individual notes can be shared publicly with a unique URL. Evernote also saves multiple versions of a document, which ensures that any accidental edits can be undone. Finally, paid users get to work offline, and can utilize the service to conduct text searches through Office docs and PDFs, as well as stored in Evernote.
