I love the CR-48's fast bootup, and I absolutely love its instant-on feature: Leave it powered on, close the lid, and when you re-open it, it's instantly on where you left off. This standby mode is easy on batteries, and it is extremely useful to me.
I just realized that anyone who gets a hold of my CR-48 will have complete and full access to whatever is open, and worse, they will have complete access to all of my Google applications because I'm already logged in. At home, this is not a problem because I trust my wife implicitly and I can control access when people are visiting. But when my CR-48 leaves my house, it's a very different story. This is a HUGE security issue for me, but there is a simple solution:
Click the Wrench icon at the top right of your screen and click "Settings". In the "Personal stuff" tab, check the "Require password to wake from sleep" checkbox. Now, when you open the lid from sleep mode, you will be prompted for your password. You can have the peace of mind that your CR-48's data, and more importantly, your Google Account data will be more secure.
