Today (6 June 2011): Evernote hits 10 million registered users
As you can tell from the numbers copied above, that means Evernote attracted about 4 million users since the beginning of this year, but more importantly, the number of premium (paying) users has more than doubled in the past 5 months (from ~200,000 to ~425,000).
The startup owes a lot of that growth to its cross-platformness: it offers native apps for Mac, Windows, Web, iPhone, iPad, Android, BlackBerry, Windows Mobile, HP WebOS — with support for more apparently on the way according to today’s company blog post.
According to Evernote, 75 percent of its user base uses 2 or more platforms to access its service (some power users apparently use as many as 10).

Late last year, the memory enhancement service (or versatile notetaking app if you want) raised a $20 million round from Sequoia Capital and Morgenthaler Ventures.
Part of that money will be spent on buying a new iPad 2 for every one of its employees – that was Evernote management’s promise if they were able to reach 10 million users by their three-year anniversary (24 June). Happy unpacking to (the more than 60 of) them.
Evernote allows users to capture, organize, and find information across multiple platforms. Users can take notes, clip webpages, snap photos using their mobile phones, create to-dos, and record audio. All data is synchronized with the Evernote web service and made available to clients on Windows, Mac, Web, and mobile devices. Additionally, the Evernote web service performs image recognition on all incoming notes, making printed or handwritten text found within images searchable.
