Someone created a pretty darn funny chronological chart (warning: harsh
language) of an OS X newbie's experience with Mac OS X. According to the nine-day chart, satisfaction can fluctuate
wildly during the early stages of Mac OS X adoption, mainly due to the "I don't know where anything is" and
"shoot, I miss my games" factors.
I have no idea who made this (I found it through del.icio.us/tag/mac), but check out the full chart for a good laugh at some of those early Mac OS X experiences.
