Maybe, but I would think that most laptops get switched off at night. Then when turned on again in the morning, anacron realizes it missed the nightly cron jobs and then runs everything.
This really does make an incredible difference to the system. If I remove the updatedb job from cron.daily, the machine won't touch swap all day and runs like charm. (That's with vmware, mozilla, openoffice, all applications that like big chunks of memory)
