Nothing unfortunate about it. There are multiple paths to success, and sometimes the path you know leads you through the mud. Nasty, yes, but far better (From a "staying alive" point of view) than the path you don't know which could lead you along a nasty cliff, and possibly over! Try rephrasing this to "When they don't keep me from delivering a product on time, I prefer the bugs I know to the bugs that might keep me from delivering and getting paid". Now, see which side of the argument makes more sense. If the bugs that I know keep me from delivering, or add significant cost/time to the development project, then I may take the leap. Or, if I can spare the manpower to carefully try the new stuff under controlled conditions, then sure. For example, Vista is the latest and greatest piece of Windows software.

Professional software development is all about managing risk. For hobbyists (and some academics) it's fine to assume the unknown risk that accompanies the "latest and greatest" release, but keep in mind that the rest of us have to keep our customers satisfied by understanding the cost/benefit ratio of these kinds of decisions.
