Top Ten Businesses the Smartphone Has Destroyed

1. With the exception of PCs, watches and remote controls, I think most of these products are already on the verge of being completely replaced.  Many of the people I know have reduced the number of devices they need by getting a smartphone.  
2. I think it is an advantage.  It reduces the amount of money you would normally spend on devices.  It also makes it more convenient because it is much smaller than many of the devices it is replacing and easier because many people use its functions in conjunction with each other.
3. Smart phones have made it easier to get things done.  With email, internet access, word processing capabilities, etc., people are able to get their work done much more efficiently while they are away from their offices .  
4. I think the most important invention of my lifetime was MP3 players and iPods.  Without the technology used in the digital media market, many of the other devices that have been made using that technology would not exist.  I think the difference between the most important invention in my lifetime and in past generation's lifetimes is that, nowadays, the focus of technology is in the entertainment industry whereas, previously, new inventions were focused more on basics such as cooking (the microwave) and cleaning (washing machines).  
5. At this point, I don't think smart phones are good enough to replace PCs.  I personally get frustrated by the smaller screen and keyboard and the fact that they have much less memory than an actual computer.  While they have some of the same capabilities as PCs, they are completely different types of devices. 
6. I still use TVs, radios, and other devices because, no matter how amazing the smart phone becomes, watching a TV show on a 3" screen will never be the same as watching it on a big screen, HD TV and listening to music using phone speakers will never be the same as listening to it with a stereo system.  While being able to watch shows and movies and listen to music on your phone is more convenient on occasion, the quality of entertainment is just not the same.
