From gee-whiz to junk

I've always wanted to go to the Consumer Electronics Show,  but haven't yet managed to find myself in Las Vegas while its been on. I try and keep up with what's hot, and what's not, and found this brief article on A Gadget's Life in the Washington Post interesting. A look at what gadgets have gone from obscure to ubiquitous - or vice versa - and how prices have changed.  The average price of a mobile phone in 1984 was $4,000, and a home PC about $5,000. Sales of standard mobiles are being overtaken by smart phones now, and mobile devices now make up the majority of personal computers sold. Worth a quick look.
