Almost one-third of mobile Web users polled by InMobi have the iPad 3 in their sights as the new tablet is expected to launch this month.
Apple's attempt to control the mobile advertising market for its iOS platform by implementing iAd has largely been a disappointment, prompting an increase in developer revenue.
In court, Larry Page and Andy Rubin said Android wasn't critical to Google's business success. Which doesn't square easily with a Google's future plans for Android ad and app sales.
