Nielsen posted today that 48% of all smartphones being used in the United States are powered by Android. This is a significant jump from this time last year but Apple still holds 32% of the US market. But 32% isn't bad at all considering that Android is an open platform that runs on countless numbers of devices which gives Android a minor advantage over Apples one or two mainstream devices. What OS do you use, are you an iPhone or Android fanboy or are you still tied to your good old' Blackberry? Leave your opinion in the comments below.
