However I don't believe that manufacturers only make what "we" want or ask for. They manufacture what they believe will yield the highest profit, and then target us through immensely slick advertising until we believe that we need what they're peddling. Once we've bought that, they'll release the new, improved, sexier version and set about making us "need" that too...
Hapiyogi you are assuming that manufacturers have more power than they do. Many is the product that a manufacturere has launched convinced will be a sure fire hit and has hit the floor with a thump. Think about Clive Sinclair's C5, John de Lorean's gull winged cars and those are just a couple of mega failures, there have been many others. Neither is the consumer as gullible as you think. The majority of people will not buy something they see no need for. Apple for all their success have also launched products that floated as well as a lead balloon. their seven biggest turkeys are: Apple Pippin, The 20th Anniversary Macintos, Macintosh Portable, iMac Hockey Puck Mouse, Apple III, Apple Newton, QuickTake 100. Have you heard of any of them? I haven't. We just do not notice the failures because they - fail.
My DGC were until very recently consumed with embarrassment because the only tv in their house was the old fashioned cathode ray tube variety. Their parents have finally replaced it with a small flat screen tv, but it is several years old and passed on by a friend. Some people do always upgrade to the newest model but the majority of people do not.
