These are downloadable apps that can synch content across multiple computers and devices.
I use the first three all the time!
- MarsEdit - blog management app for Mac (not free, but worth every penny)
- Dropbox (synch a range of files across multiple devices)
- Evernote - note management for Mac, Windows, web, and mobile
- Simplenote - simple note app for web and mobile (synchs with Mac or Windows through separate apps)
- Notational Simplicity - Mac app for synching Simplenote
