It's oftentimes easy for us to get swept up in Android mania and forget that Google's mobile platform is still in its infancy. Then we get cold hard numbers like these -- showing iPhone OS owning 28 percent of the US smartphone market and closing in on RIM's leading 35 percent -- and we face up to the realization that Android handsets still account for less than one in every ten smartphones owned by Americans today. In spite of collecting 28 percent of all consumer smartphone purchases in the first quarter of 2010 ( according to NPD ), Google's OS was only able to climb up a couple of percentage points in terms of total market share, showing just how long a road lies ahead of its world-conquering plans. Guess that now explains why Apple's response to the earlier numbers was so nonchalant Other intriguing figures include a high rate of loyalty among iPhone OS and Android users, with 80 percent of the former and 70 percent of the latter expressing a preference for the same OS in their next phone -- both rather shaming Microsoft and RIM's numbers, which were a mediocre 34 and 47 percent, respectively. Funnily enough, despite its inflammatory title, this report finds Android and iPhone users are more similar to each other than anyone else -- an uncomfortable fact for both parties to deal with, we're sure.
