one of the features that i’m digging from osx is filevault. macdevcenter has a good article about it, but basically its a seamless way to encrypt your home directory in osx. the performance hit from processing files in an encrypted disk image is rarely noticeable, but then again i’m not really doing anything that’s i/o intensive. also the amount of time filevault takes to regain free space when you log out seems to take forever sometimes.

i’ve played with disk images a lot in the last few years, and i’m impressed with how apple pulled it off. i wonder just how much of a storage hit you take by having to uncompress the disk image when you log on to osx. the stock 40gb harddrive in this ibook is starting to fill up and i’m already eyeing 100gb laptop harddrives. it’s gonna be a pita to install another harddrive and i don’t feel like carrying around an external harddrive. bleh.
