The marketplace now has nearly half as many applications as Research in Motions BlackBerry App World, leading one Windows Phone 7 fan website to declare it to be the third biggest app store among U.S. customers behind Apple and Android if you just count “real apps.” In February, RIM said it had more than 20,000 apps available and noted that BlackBerry smartphone users are downloading more than 2 million apps per day from BlackBerry App World.
Microsofts Windows Phone 7 Marketplace is likely to become more popular as U.S. mobile operators like Sprint Nextel introduce more devices that feature the operating system. Sprint will offer a handset from HTC later this month that includes Microsofts new operating system.
Having only debuted last fall, Microsofts Windows Phone 7 OS might have a long way to go before it poses a serious threat in the U.S. smartphone market to the likes of Apple, Google and RIM.
The NPD Group, a market research firm, reported in January that Microsofts system controlled a modest 2 percent of the U.S. smartphone market in the fourth quarter based on unit sales.
