I know it's the trend to talk about "smartphones" as if it was a revolution but it's not. Actually the concept of smartphone is a marketing term used by some manufacturers to advert and differentiate their products but in reality, it's just the high end class of phones. This class has existed for more than a decade. in 2000 we were surfing the web in text mode over the wap, i-mode, etc... and we were using J2ME applications for everything. This class of phones has been sold by billions since a long time ago. There were like 100 phones for 1 PC in 2000. I'd even say there are LESS phones sold these days than there were in 2005.
So modern "smartphones" are far more capable than the previous ones, that is true but the previous ones still qualify as computers or the Apple II does not.
As an ex-user of Psion PDA's and Nokia 9000-series Communicators I'd have to agree. There is simply no decisive changeover point between a "featurephone" and a "smartphone".
For may years now even basic phones have played media files, browsed the internet, taken pictures, and run "apps". The move from dedicated PDAs and phones towards single units was not "revolutionary" but rather a gradual process that began in the early 1990s, many years before ~either~ Apple or Samsung were making smartphones.
My point, the line between PDAs, basic phones, smartphones, and other devices has always been thin and gray.
