Newton Rollout -- One caveat to all the Newton comments you hear in TidBITS and other publications. It appears that although the Newton was introduced at Macworld Boston, the official rollout will take place in about two weeks. The practical upshot of this is that dealers won't have any Newton MessagePads for sale until that time.
Untrash the Trash
Feeling trasher's remorse? On Snow Leopard, you can open the Trash (click the Trash icon in the Dock) and "untrash" individual items there. Select one or more trashed items (files and folders) and choose File > Put Back. This returns the items to where they were when you originally put them in the trash. The keyboard shortcut is Command-Delete - the same as the shortcut for trashing an item in the first place, since in deleting something from the trash you are untrashing it.
