The marvel about Electronics is the rapid changes that never cease to produce improved products in the market all through the year.
There was a time when the bulky battery operated Transistor hand held radios did not cause much of a stir because their models would take several years before a change was made.
This is evidently not true anymore. Take for theipods for example, in under six months I have seen my younger brother acquire three different models from the same Manufacturer.
I notice that his models were slimmer and had more pleasant colors with every new change he made. I am told that the Electronic functions were enhanced for every model and provided better product protection.
