Vacuum Cleaners Discussions

Who thinks the day will come, and how long will it take, when the "vacuum cleaner" will generally be accepted as just a hole in the wall that we plug a hose into? No more cyclones, water baths or super-duper filtering for alllergy sufferers.  No thought over buying canister or upright and what warranty length is.  No more concerns about cord length or operating noise levels.  I'm not just talking central vacuum system but also of a possible change in our view of practicality.  The day is not that far away when our computers will also be our telephone and TV among other things.  Come to think of it they are now though not widely employed.  Does anyone feel central vacuum systems may one day be provided in apartment buildings and other multiple dwelling as a given as well as in individual private homes?

Thanks,
