That quote is unfortunately true of so many products.The ludicrous unsustainable yearly development cycle has only made this worse....
With regard to FileMaker, I've been an ardent fan since Version 2.1. While this "phenomenon" happens to many products, it hurts that much more when it happens to products with such a long history, like FileMaker, or the Mac OS itself.
On the other side of the coin, even Windows is suffering from the blistering pace of modern development. For the good of users everywhere, I dearly wish this "trend" would stop! Apple would sell way more iPhones if iOS had the reputation it deserves rather than the one it has.
The thing that puzzles me is the fact that shareholders (of any tech company) don't seem to grasp the idea that such a change would ultimately be beneficial for them, as well.
