When you take into account the R&D time involved, the products currently on the shelves already have 2 or 3 new generations heading toward production. Some call it planned obsolescence. Couple that with the rapid advances in technology and we soon realize the pressure being exerted on manufacturing to meet demands for "the newest and best - the latest and greatest" in new products. In my humble opinion, the market is being driven by teens and early 20s consumers which is creating many interesting techno gadgets. We all benefit by those gadgets. Example: Nearly everyone in this nursing home, including those in their 90s, seems to have a cell phone and many have GPS although they aren't going anywhere. They use them to find the dining hall I guess. LOL
