Firewall Your Mac (New in 2nd Edition!)

Level: Easy
Platform: Mac OS X Leopard

"Surprisingly, your new Mac doesn't ship with its firewall turned on by default. That's not a problem if your Mac accesses the Internet through another device that has a firewall on, such as a wireless router. But if you connect your Mac to the Internet at public wireless hotspots, or plug it directly into your broadband Internet connection, you should enable the firewall to avoid unwanted connections from other computers."

Speed Up Windows Vista with a Thumb Drive (New in 2nd Edition!)

Level: Easy
Platform: Windows Vista

"The best way to make a computer run faster is to add more system memory, or RAM. But not all computers have expansion slots available for additional memory, and installing internal memory sticks can be an intimidating undertaking for those who've never opened their computer and faced its silicon innards. That's why Microsoft introduced a new feature into Windows Vista called ReadyBoost, which lets you add memory to your PC with a regular USB flash drive."
