When you look at the latest Net Applications numbers, you see a completely different story from the one at comScore. According to Net Applications, of the mobile and tablet operating systems banging against their 40,000 tracked sites, only one-half of 1 percent of the hits came from mobile devices running Windows Mobile or Windows Phone. The lion's share of mobile Internet access comes from iOS at 53 percent, Java at 21 percent, and Android at 16 percent.
More than that, the Windows share of online access is still falling. In August 2010, Net Applications reports, Windows Mobile drove 1.5 percent of all Web access. By August 2011, the share fell to 0.6 percent, and in September, it was under 0.5 percent.
So is Windows on the mobile platform growing, stagnating, or still headed to Hades in a handbasket? How does one reconcile comScore's 5.6 percent self-reported U.S. handset market share with Net Applications' measured 0.5 percent international Web access? Tough questions, and I don't see any clear answers. But I have a few observations.
It's possible that iPhone and Android users just surf the Web one or two orders of magnitude more frequently than Windows Phone and Windows Mobile users. That doesn't seem likely, but it's possible. It's also possible that Web surfing on the iPad has skewed all of the numbers completely out of whack. I don't think that accounts for all of the discrepancy, though, because iOS usage is "only" at 53 percent.
While comScore doesn't break out old Windows Mobile counts from new Windows Phone counts, Net Applications does. According to Net Applications, Windows Phone -- even now -- accounts for less internet access than Windows Mobile. Surprising, but true -- it's entirely possible that comScore is seeing and counting a lot of old Windows Mobile phones that aren't being used online very frequently.
The only way I can figure to make some sense out of the numbers is to take into account how many new Windows Phone devices are being activated. It's relatively easy to estimate roughly how many iOS and Android devices are coming onstream -- Apple and Google brag about their numbers from time to time. But there hasn't been a hint from Microsoft.
Last week, Windows Phone head Andy Lees spoke with AllThingsD about Windows Phone. "We're not making specific predictions but I think that our momentum is going to build," he said. He gave us no numbers, past, present or future.
With Android activations in June running 500,000 per day and iOS activations running an estimated 350,000-plus per day (Tim Cook says Apple sold "more than 33 million iOS devices" in Q3), Microsoft has a long way to catch up. Whether Mango's up to the job is anyone's guess -- "guess" being the operative term until we get hard numbers.
