Life Hacker compares the BitLocker encryption feature from Microsoft's new Windows Vista with the FileVault feature in Apple's Mac OS X:
Both BitLocker and FileVault are built into the operating system, and they take different approaches to solving the same problem. But if BitLocker and FileVault went head to head in an cage match, who would emerge victorious? Let's take a look.
Caveat: Some might say that this is an apples to oranges comparison; others will say a more fair head-to-head should be between the yet-to-be-released Leopard and Vista. They may be right. Grains of salt are available at the gate. Also, Windows Vista offers individual folder encryption separately from BitLocker.
