I have had Lion installed for five days, I installed it this past Wednesday. Since then, I have noticed that Lion is slowly chipping away at my boot volume's free space. In the five days that I've been using Lion, it's chipped away nearly 3GB of disk space. All I have been doing is web surfing in Safari, using Mail and iCal, and occasionally using iTunes. Time Machine is turned off. I would assume that Auto Save and Versions are the culprits but is it realistic for the os to eat up that much space with that kind of light usage? Also, is anyone else experiencing this?
