Apple has released two updates for recent MacBook models that address several stability and reliability issues. The MacBook Pro Software Update 1.4 introduces changes that improve the reliability of graphics rendering and external display support, as well as Thunderbolt device support. The MacBook Pro EFI Update 2.1 seems to have a similar set of targets, but also resolves an issue with Turbo Mode in Boot Camp. As always with firmware updates, do not disturb or power down your MacBook Pro while installing, since it could leave the Mac in a non-functional state. Both updates can be downloaded and installed via Software Update, or through their individual pages on Apple’s Web site. (Free, 132.69 MB and 3.06 MB respectively)
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.
