This seems the case with an os upgrade. Some people have problems, and other don't. The thing to remeber is, dont install the new OS on day 1, wait a couple weeks and read things like this forum, macnn, and other mac related web sites, and then the problems that are found will be very obvious, so you know what to avoid. The success rate with installing an OS is pretty high, just the bad stuff gets reported. -See Yea!
