last month's report, it's more or less business as usual in ComScore's latest smartphone market share numbers for the three-month period ending in October, but there are a few interesting points worth calling out. Most notably, RIM's decline seems to have accelerated -- they've lost a claimed 3.5 percent of the US market in the latest period compared to 2.8 percent prior, which means they're now down to 35.8 percent. Of course, that's still more than enough to keep them comfortably in first place, but it's a situation they're going to want to reverse sooner or later -- hopefully with TAT's help. Meanwhile, Apple's tacked on a slightly larger slice of the pie, but they're still holding fairly steady; Google, meanwhile, continues its stratospheric rise, tacking on another 2.1 percent since last month's numbers to hit 23.5 percent -- nipping on Apple's heels, we'd say. The most intriguing story, though, would have to be Microsoft: they're lower than before at just 9.7 percent of the market, but these figures don't include Windows Phone 7 yet -- and clearly, no one's buying WinMo 6.5 gear at this point. Should start to get interesting in the next month or two on that front.
