Bear in mind this is an analyst view and not neccessarily gospel.
In a nutshell:
Apple stalls (but still massive)
Android continues to grow (biggest but given all the devices not surprising)
Windows doubles (still small but decent trend obviously)
Blackberry droped like a stone and is almost dead.
I am looking forward to release of individual manufacturers numbers for the 1st quarter of 2013. Samsumg will doninate smartphoens, Nopkia and Samsung will dominate all phones and Nokia should see continued growth in smartphones.
Apple iPhone sales stutter as Microsoft Windows Phone market share creeps up

Sales of Apple iOS device sales have stuttered, allowing Windows Phone and Android to grow their share of the market, according to analyst firm Kantar Worldpanel ComTech.
Kantar revealed that Apple has suffered a 3.5 percent drop in global sales during the first quarter of 2013 compared to the same period last year.
Despite the small drop Apple still remains the second strongest player in the smartphone market, controlling a sizeable stake at 43.5 percent.
Above it, Android retained its dominance accounting for 51.2 percent of smartphone sales, marking a 5.8 percent growth on the figures recorded in the same period last year.
Below the two giants, Microsoft's Windows Phone remained a fringe player in the market despite nearly doubling its share, accounting for 4.1 percent of recorded smartphone sales.
Meanwhile, BlackBerry sales continued to plummet despite the release of its new Z10 smartphone and BB10 operating system, dropping to 0.7 percent.
BlackBerry accounted for 3.6 percent of recorded smartphone sales in the same period last year.
Kantar Worldpanel ComTech analyst Mary-Ann Parlato attributed Android's ongoing dominance to interest in its Galaxy range of smartphones.
"It was thanks to Samsung's price drop at the back end of 2012 that led various smartphone and feature phone users to upgrade to a Samsung device," said Parlato.
"It's apparent that Samsung is successful at capturing users from across the competitor set and not just gaining from their own loyalists - albeit loyalty towards Samsung has also grown."
Kantar's findings mirror those of other research houses. Prior to it competing research firm Gartner reported that Apple and Samsung's combined share of the market grew to 52 percent in the last three months of 2012, up from the 46.4 percent figure recorded in Q3.
