Over at Macworld, Andy Ihnatko ponders whether Lion’s sandboxing feature might mean that one of Apple’s best babies — interapplication communication — is being thrown out with the bathwater.

Fun Way to Send Attachments in Mail
If you're working in a file that you want to attach to a message in Apple Mail, you can transfer the file to Mail easily: From the title bar of the file's window, drag the little proxy icon to Mail's icon on the Dock. Your Mac will make Mail the active application and open a new outgoing message, with the file attached.
(If your icon won't drag, the file probably isn't saved.)
