????美國咨詢公司高德納（Gartner）于上周三發(fā)布了《全球手機(jī)銷量》報(bào)告,，IDC和康姆斯科（comScore）緊隨其后，雙雙于上周四發(fā)布了彩色柱狀圖,，表明各自對智能手機(jī)大戰(zhàn)當(dāng)前戰(zhàn)況的看法——IDC（上）分析了全球市場,，而康姆斯科（下）則分析了美國國內(nèi)市場的狀況。

????筆者的見解是：

????? 以上兩張圖表都清晰地表明,，智能手機(jī)市場已呈兩虎相爭之勢,，不論是在美國國內(nèi)還是全球市場，蘋果（Apple）iOS和谷歌（Google）Android都占據(jù)了90％以上的市場份額,。落敗者們看來唯有期盼奇跡才有可能追上,。

????? 雖然Android的全球市場份額在2012年增至約70％，但據(jù)IDC和高德納（參見下方統(tǒng)計(jì)）的數(shù)據(jù),，Android的增速在第三季度趨于平穩(wěn),。關(guān)于這點(diǎn)，IDC的季度圖（上）比康姆斯科的3個(gè)月平均變化圖（下）更明顯,。

????? 雖然蘋果在2012年底的全球市場份額（約21％）小于它在2011年年底的份額（約23％）,，但從IDC的柱狀圖中可以看出，上個(gè)季度,，隨著iPhone5發(fā)布,、iPhone 4和iPhone 4S降價(jià),，蘋果的市場份額再度呈現(xiàn)上升態(tài)勢。

????IDC和高德納的數(shù)據(jù)統(tǒng)計(jì)如下所示：

????Hard on the heels of Gartner's Worldwide Mobile Phone Sales report Wednesday, IDC and comScore both released colorful bar graphs Thursday representing their view of the current state of the smartphone wars -- the world war (top) from IDC, and U.S. war (bottom) from comScore.

????A few observations:

????? The extent to which the smartphone wars have become a two-man race is clear in both charts, with Apple's (AAPL) iOS and Google's (GOOG) Android controlling more than 90% of both the U.S. and the worldwide markets. The also-rans would have to execute sharp uphill sprints to catch up.

????? Although Android's worldwide market share grew to approximately 70% in 2012 according to both IDC and Gartner (see spreadsheets below the fold), Android's rate of growth leveled off in the third quarter. That's easier to see in IDC's quarter-by-quarter chart (top) than in comScore's three-month moving average (bottom).

????? Although Apple finished 2012 with a smaller global market share than it enjoyed at the end of 2011 (about 21% vs. about 23%), you can see in IDC's bar graph that it was re-gaining share last quarter, after the release of the iPhone 5 and the price cuts on the iPhone 4 and 4S.
