Microsoft suffered for years over backwards compatibility with DOS. MS wanted to move forward with their OS at a quicker pace but there were so many "critical" apps running under DOS that talked directly with the hardware, that no one wanted MS to depricate it. Windows 95 was supposed to be the first version of Windows to break the chain, but had to retain some functionality still. Even Windows 98 was still bound in some ways with DOS.
The point is, you have the right to expect backwards compatibility... to a point. Where is that point? Well let's see, how long ago did Apple stop suporting 32 bit OS? As far as I am concerned, that is the point beyond which backwards compatibility is gratis.
