Ok, so I've decided to create a showdown between my mac and my PC to see which one crashes more often. Here are the rules:

* All crashes however insignificant are reported, including application crashes. Information about the crashes will be posted, including any details on the causes or the frequency by which this has appeared elsewhere (if possible).

*A running total of Hard Crashes and Soft Crashes for each machine will be kept at the end of each entry.
