I am using Smartphones for quite awhile now, almost 11 years, I think, no I am sure! My first smart phone was HP iPAQ hw6510, and that was one of the world’s first devices which had a GPS, a phone, and tablet functionality in one device. After owing several iterations of Smartphones, more than 15 in last 11 years, I still think Smartphones are a failure, if not a complete failure then at least a partial failure in incorporating new technologies and improving already present technologies. For me, if someone with a potential cannot do his/her best that is a failure. I don’t deny their success or importance, but as a device they could do much better than what did. Let’s go back to 2010 and imagine we have the original Samsung Galaxy S, is there anything which Galaxy S could not do and Galaxy S6 can do?
Among many others, following are the reasons which compel me to the conclusion that Smartphone makers have failed to produce awesome devices and these money making giants- Apple, Samsung, LG-need to do a lot better before they could claim that they have produced a perfect, or a near perfect, phone
