If you have a number of computers and are constantly switching between them you might run into a situation where you cannot keep straight which computer you are saving files to. Syncplicity looks to help solve this problem by creating an application that installs on one computer and syncs all your documents, photos, and music by backing them up online with remote access and history.
If you install it on additional computers it will synchronize your files so that you have access to all your files across all your computers. Currently the product is available for PC users with a Mac version in the works. I cannot wait to check out as it sounds like a great complimentary service to MobileMe as it helps to bring your files with you and it even backs up and sync your photos from Facebook and your Google Docs.
