Is any technology fully developed before it is replaced?

I've just found an old Windows '95 disk - why didn't they fully develop that before bringing out a new product?

The easy answer is to be cynical and suggest Mfrs just want to chase profit. That may be partly true, but sometimes it's better to start over with a platform that will be easier and faster to advance and keep up with the opposition.

However, spanner is right - we'll all feel a bit cheated if Maemo is pushed into the sidelines and Meego is exhibited as the Great White Hope...
