Filevault is okay for protecting your data from being stolen when your laptop is. It only encrypts your home directory, so you have no assurance about the integrity of the rest of your system. If you're only worried about getting your laptop stolen, not a big deal. On the other hand, if you're super paranoid that someone came in and tainted your system when you were away from your computer for 10 minutes, maybe you want a different solution. Of course, usual advice applies (strong passwords, including the master password if you set it)
