Evernote on Windows, is a desire for a faster interface. Our wish has been granted. Evernote 4 is awesomely fast. I've been using a Beta for the past couple weeks and love how fast it is at jumping to new notes when you switch Notebooks, and when searching.
Check out all the details on their blog and download it here.
Evernote's goal for this release was to recreate the features of 3.5 in a faster client, and a cleaner interface. On their forum they say they will soon " start work on the list of long awaited feature that include sharing, due dates, templates, note links and more."
I'm real jazzed about Due Dates. I've use Evernote now as my personal task program, so Due Dates will be a big plus.
