Across the various corners of the Internet, I've been reading about how PC's will eventually be displaced by smartphones, because (apparently) smartphones sell more units. Well yes, EVERYONE has a phone these days; they are essential tools for communication while out and about. But the two devices serve very different purposes. PC's are used for content creation and business, smartphones are used for mobile communication (talking, texting, Twitter, etc.). Yes, they both connect to the internet, but that's where the similarities end.
The main problem with smartphones is how unstable the apps are. Smartphone apps crash often (most likely caused by poor coding and memory mismanagement), and their app stores are filled with junk apps made by inexperienced developers.
Also, an oversaturation of devices with different hardware configurations makes it difficult for many people to update to the current software (you never know which device will receive an update). Granted, most of the update problems stem from carriers and manufacturers delaying updates, but you'd never see these problems on a Windows/Mac computer, because Microsoft/Apple control the update distribution themselves.
So I ask, aside from mobility, what's the advantage of owning a smartphone over a computer?
Now if we were comparing tablets to PC's, then it might be a better comparison. We're already seeing Android and Windows tablets that can successfully mimic a PC (both OS and hardware). Microsoft is (ironically) helping to change the landscape (transition?) from PC to tablet, but I highly doubt PC's as we know them will ever go away. They are much more stable and reliable than tablets, at the moment. Plus there's the fact that a majority of businesses and schools use computers for day-to-day tasks.
