Vemedio has released version 1.2 of Instacast for Mac with a new architecture for synchronizing podcasts between your Mac and iOS devices. By sending smaller bits of data, this new scheme ensures that all your devices are synced with the same state while also saving on network traffic, storage requirements, mobile data charges, and battery power. You’ll need to update to version 4.5 of Instacast for iOS to continue syncing your podcast subscriptions to your iPhone, iPad, or iPod touch. ($19.99 new from Vemedio and the Mac App Store, free update, 7.0 MB, release notes, 10.8+)

In Snow Leopard, Option-clicking the Volume icon in the menu bar displays a list of sound input and output devices. Choose one to switch to it; it's much easier than using the Sound preference pane. Also, hold Shift and click the icon to set the system volume, which is separate from the general output volume.
