I bought into the Simplenote world from the moment I read John Gruber rave about it. Since then I have relied heavily on the Simplenote platform for both personal and professional note taking and list making. The beauty of Simplenote lies in its unique restriction to plain text. I have been tempted by the luxuriousness that is Evernote. However, after a brief project to extract all of my notes from Evernote into a file structure that would outlive the hosted service, I realized that there was safety in simplicity.
OmniFocus from Windows
There's no doubt that OmniFocus by the Omni Group is the quintessential mac app. It's elegant, easy to use and simply makes work easier. It has nearly solved the digital ubiquitous capture problem. It's an iPhone app, it's an iPad app, it's desktop app, it's a whipped topping. Unfortunately it is not a windows app (yet).I spend most of my work hours on a Windows machine. I have developed a couple of rountines that allow me to integrate OmniFocus with my workflow on Windows.
I think a large number of folks have already established the Pinboard.in is an excellent bookmarking service. Now, comes the task of getting immediate and convenient access to those bookmarks. I have been happily using the app DBD Delicious Bookmark Discovery ($1.99 on the Apple app store) for that very purpose. While the name indicates that it is a tool for Delicious bookmarks, it is a top notch tool for accessing Pinboard bookmarks.
