Unconfirmed: Microsoft sold 40,000 WP7 devices on launch day

According to The Street and “a market research source who tracks phone sales,” Microsoft sold roughly 40,000 Windows Phone 7 devices on Monday in the United States. The phones also debuted in Canada but it’s unclear if The Street was including that in their statement.

In perspective: Google says that it sells about 200,000 Android devices a day (though the first Android device did not fare too well) while Apple claims it sells on average 110,000 (as of last year, this year’s numbers could be highly inflated). The Street’s analysts source Monday as a huge impairment to the new operating system’s launch.

Microsoft didn’t help itself much, said Michael Cote, an industry strategist with the Cote Collaborative. “Mondays aren’t great launch days. They poured all that cash into it but they lost track of the fact that Fridays or Saturdays are the best launch days,” said Cote.

Michael Cote also believes that the variety of devices may have confused many consumers, though AT&T is the primary launch partner and is the carrier featured in all ads. Regardless of how many devices Microsoft sold, AT&T and T-Mobile have both stated publicly that they are content with the amount of demand and interest, though both companies have declined to release sales numbers.
