Thanks to a rich marketplace, consistently good apps that are featured in the App Store, and the constant attention blogs like ours bring to developers and consumers, the iPad has had its fair share of owners downloading tons of applications. Not only did iPad users download more than 3 billion apps from the App Store since the iPad’s launch in 2010, developers published 120,000 apps specifically for the iPad in the third quarter of 2011. ABI Research notes that iPad downloads are only 19% of all the cumulative downloads by Apple users. With lots of choice and a device that just works, users are eager to try out the latest innovations in touch-based software.

In comparison, Android users have only downloaded 440 million applications. It could be that there simply aren’t as many Android tablets in consumers’ hands as there are iPads, or it could because that developers simply aren’t making apps formatted for the tablet experience like they are on the iPad.

According to Lim Shiyang:

Discounting all those apps that were originally developed for Android smartphones, Android still trails greatly behind the iPad in terms of its tablet app offerings. Many Android tablets in the market are still using older versions of Android, which disadvantages users from enjoying the better effects of apps produced from more advanced software development kits.

As for Android’s phone ecosystem, ABI Research expects Android users to rack up 58 billion app downloads by 2016, compared to only 27 billion by iPhone users.
