I've had little experience with Mac OS prior to OS X, but I do recall the little wristwatch mouse-pointer indicating "think time". In OS X, this has largely been replaced by the delightful spinning beachball. However, sometimes the wristwatch rears its ugly head. What's the relationship between the two? Is there a historical or programming reason why the wristwatch appears? I thought OS X was completely new wrt OS 9 and earlier - why contine with the relic wristwatch? Just curious!
