I've experienced two of the bigger problems (requiring a forced restart) mentioned in this thread:
The (rare, but still) problem where the MacBook Pro I have won't go to sleep when closing the lid/screen and then not being possible to "get back on" (black screen won't come on).
A couple of times it has happened that I've put the computer in my racksack (thinking it was asleep), only to later find the computer burning hot with fans going like crazy. This also happened in Tiger though.
I've also had the "one app freezes (beach ball) and spreads to other apps, force quit doesn't work" issue happen two times on my MacBook Pro and one time on my old Quicksilver G4. A vary rare thing this is, but since others are reporting it I think it's a software thing in OS X.
I use both the MacBook Pro and the G4 extensively every day, and most days things are just fine. Over all everything works well, but forced restarts are something that belongs to the 20th century.
