Again, BB and Symbian had few appreciable 3rd party apps, and very limited in-house apps, so I don't consider them smartphones, which are functionally full-featured computers in a handset sans the desktop or laptop screen. At best, they were feature phones with a bit of additional functionality.
Oh, BULL PUCKY! You obviously did not ever own a Blackberry or a Nokia phone circa 2007-08! And you claim the Microsoft phone had THIRD-party apps. More BS. All phones of the period had to download their apps from their carriers, but the sheer number of apps for Rim Blackberry and Nokia was quite high for the period. Blackberry had quite a few third party apps, especially for business use that were downloadable. Vlingo, RTM Blackberry app, WSJ mobile app, Gmail, Google Maps, Google Talk, Google Search, Skype, Viigo, MobiPocket Reader, VyMail client for YouMail, and MobileTraffic.tv are all third party BB apps that come to mind, Nokia was pretty in house, but also had independent developers on Symbian, too. You just DON'T want to count them. The Windows Phone of the period was a joke to those who tried to do anything serious with it, yet you count it.
Add the sheer numerical distortion in the chart you posted, where ever you cut and paste it from, demonstrates clearly that even liars can make cherry picked lying statistics. They just won't stand up when an Economist who knows how to read data sees the clear obfuscation going on. You can try pulling the wool over ignorant know nothings, but it won't work with trained, educated people. I'm calling you out on this and your other posts.
You don't get to define "smartphones" to fit your pet theory, especially when your experiential data with those phones you say did not have "appreciable' 3rd party apps, your criterion for these phone's exclusion, seems to have been made up out whole cloth by YOU, based on no first hand evidence. Instead, you choose to bestow your blessings on a platform every contemporaneous user hated, Microsoft Mobile, and declare it a "smartphone", when most users of the product would laugh you out of the room!
Incidentally, your source article at Wikipedia claimed both the BlackBerry and the Nokia N series to be the pre-eminent smartphones of the period prior to the intro of the Apple iPhone. . . . when you in your FOLLY chose to exclude them to obfuscate and advance your pro-Android agenda!
