When you have a product that hasn't actually changed in 5 years its easy to make it stable, especially if it doesn't actually do a great deal in the first place, and even then what it does is bloated, outdated, and inefficient. But where would we be if everything was like that. We'd still be driving Model T fords, and forget Television, the Internet and all the other offerings that have had to briefly go through the "not so stable" stage.

I'm just glad that everyone doesn't have that blinkered approach to things, or progress would come to a grinding halt!!!!!
