Just a quick note on bookmarks. I use several laptops, a common machine at home and a workstation at work. This can sometimes get confusing when I save web bookmarks in various different places.
I recently discovered <a href="http://www.foxmarks.com/">"foxmarks". I only used Firefox, and foxmarks is an extension which syncs up my bookmarks everyplace I install it. It's very handy.
I also discovered "gmarks", which places the bookmarks in a window on the left makes them easy to use. I'm still on the fence with gmarks
Sometimes I wish there was a way to make cross platform "notebooks" with firefox, which would combine a directory tree under SVN control, bookmarks, pdf and an email folder all into one. And make it easy to archive.
