i got fired once. i drank a lot and thought about how nice it was to be gainfully employed. then i did some introspection and realized that the cues were there a year before. i should have quit when i had the urge and i still looked good, because as time went on i hated the work and finally the management caught on. i could have used the good reference.
apple laptops ≠ linux machines. in fact, most of the new macbooks are quite hard to get running on something modern like ubuntu 10.4 LTS, and just because OSX is a derivative of BSD doesn't make it friendly with current linux versions. especially those macbooks with "automatic graphics switching" and the like. sure you can boot, but all the [proprietary] advanced [closed] features that apple adds don't really function at all.
