It looks increasingly like Android will be the major challenger to both Apple's iPhone and iPad.
In the tablet market, Apple's iOS has a commanding lead, while Android is the only other OS that registers a market share in double digits. In the smartphone arena, there are other significant competitors, such as BlackBerry and Windows. However, BlackBerry market share is dropping, according to comScore's latest survey -- in fact, Apple surpassed RIM in comScore's April report -- while Microsoft has yet to make much of a dent.
How do Apple's iOS and Google's Android stack up head to head? We look at the numbers.
Tablet market share
The iPad held a commanding 83.9% of the worldwide tablet market last year, with Android tablets far behind at 14.2%, according to Gartner. Other stats show a similar healthy lead. For example, a recent Modelmetrics Web survey found 83% of respondents planning to roll out iPads in the enterprise and 34% with plans for Android tablets.
However, Gartner expects the market-share difference to narrow considerably over the next few years, with iOS holding 47.1% by 2015 and Android growing to 38.6%.
Bottom line: iOS should remain the market leader for the next few years, but Android is expected to grow considerably -- largely at Apple's expense.
Smartphone market share
Despite its reputation as a groundbreaking smartphone when first introduced in 2007, the iPhone doesn't have the market clout of the iPad. Apple has slightly more than a quarter of the U.S. smartphone market, according to a comScore MobiLens report, but IDC estimates just 15.7% of the global pie .
And some analysts expect the iPhone to slip worldwide in the coming years as both Android and Windows Phone gain traction. IDC predicts that Windows Phone will be the No. 2 OS behind Android worldwide by 2015, with iOS in third place.
Latest stats from comScore show that Android became the U.S. smartphone market leader early this year, overtaking Research In Motion's BlackBerry. The iPhone was third. Google said in April that there are now more than 350,000 Android smartphones activated every day.
Bottom line: Google's Android has done an impressive job of surpassing Apple in the smartphone market, despite the iPhone's early lead.
