A report from the analytics firm Flurry, based on publicly available market news, has found that Apple and Google have 34 percent of the portable gaming market.

According to the report, game revenue in the U.S. is fairly flat, but portables have been attacked from both ends by mobile and consoles.

At the Game Developers Conference last month, Nintendo President Satoru Iwata said that smartphone games were hurting the industry with low-quality, low-cost games. Of course, Nintendo has the most to lose here, as its main competitors have mobile options for their games.

Microsoft told gaming blog Kotaku that the Windows Phone 7 is its mobile gaming platform. And Sony is launching the Xperia Play, the phone that also has PlayStation controls.

Nevertheless, Nintendo told CNN this month that it isn’t interested in making a phone right now. “We don't see that as an opportunity,” Nintendo of America President Reggie Fils-Aime told CNN. “Phones are utilities. Phones are not by definition entertainment devices.”

Flurry’s report pours a bit of cold water on that statement, particularly as notable game companies such as Square Enix start to design high-quality games just for phones.
