Being a computer user that switches between Mac and Windows everyday, I am always searching for tools that will allow me to share information between the different computers, as well as platforms. Over the last month I have drastically simplified this issue by the addition of Foxmarks and Dropbox.
Foxmarks is a Firefox add-on that originally syncs and backs up bookmarks. Since I use Firefox as my primary browser on all computers, having them sync is important. I use to use the Google Sync tool until it stop supporting the new Firefox browser, and in fact, Foxmarks does do this better than Google Sync did. Recently Foxmarks added the ability to sync passwords as well. I have had success with this on all of the computers except my office XP box. It continues to ask for my PIN to sync passwords over and over. This does not happen on my other XP/Vista/OS X computers however, so am unsure what the issue is?
Dropbox has been a great tool. It syncs specific folders in real time very quickly so I can have my KeePass and KeePassX synced between all the computers, as well as, my IE favorites folder.
I find Dropbox faster and easier to use than JungleDisk, however, Dropbox has a 2GB limit. So I do not use it to sync my music collection and the like. I highly recommend Dropbox to anyone.
