Prices on electronics in general have been sliding down a steep slope for decades, owing to automated mass production and ever-increasing integration packing more and more functionality onto smaller and smaller wafers of silicon. Back in the 1950s a typical B&W TV would set you back several months earnings from a good family wage job. There was a reason only the extravagantly rich had more than one. My dad's first electronic calculator was over $400 in the 70s, just a few years later you could buy a similarly capable unit for under $30, and by the 80s they were given away as free promotional items.
Everyone may be broke, but look in the dumpiest trailer parks in the poorest areas of the nation and you'll still see a few satellite dishes, flatscreen TVs, DVD and blueray players, mobile phones, video game systems, laptops, etc.
