Windows only: Avanquest Connection Manager, previously a $US30 app, is now a free utility that could be seriously convenient for laptop users. The app lets you create profiles for your different wi-fi or LAN connections, changing email, printer, and network drive defaults depending on where you hook up, along with security settings and other concerns. The app's basic connection-chooser is also more user-friendly than Windows' own somewhat plain built-in version (though that might be what some road warriors like about it). The trade-off for its "free"-ness appears to be ads for other Avanquest software scrolling across the top, but I find them pretty easy to ignore. Avanquest Connection Manager is a free download for Windows systems only.
