Apple iPad sales are reportedly one of the strongest points for Apple earnings, according to a survey conducted by market research firm Strategy Analytics.

Strategy Analytics director Peter King reported that: "Global tablet shipments reached 24.9 million units in Q2 2012, jumping 67 percent from 14.9 million in Q2 2011. Demand for tablets among consumer, business and education users remains relatively healthy. Apple shipped a robust 17.0 million iPads worldwide and maintained its strong market leadership with 68 percent share during the second quarter of 2012."

The Cupertino giant took a small piece of market share from Android, with Apple's share in the tablet market rising from 62 percent to 68 percent in the second calendar quarter, reaching its highest level in two years. Reports said that "Apple continued to shrug off the much-hyped threat from Android and the iPad's global tablet share is at its highest level since Q3 2010."

Despite a roaring success in the smartphone arena, Android devices are still adapting into the tablet market. Android tablet shipment has only grown to a mere 7.3 million units in spite of top notch companies like Amazon, Samsung, Acer and Asus backing its hardware section.

However, Google Nexus 7 filled this gap created by other Android tablets. Nexus 7 tablets were reportedly sold out in US and UK, and its sales are expected to catch up with Amazon Kindle Fire. Priced at $199, the Google tablet comes with high end specifications including a quad-core processor, Android Jelly Bean OS and Google Now, which is similar to the Siri voice recognition feature found in Apple devices.

Meanwhile, it's reported that Apple is planning an all-out attack against other tablets with the launch of its 7-inch iPad mini, which is expected to release following the debut of the iPhone 5 sometime this year.  Amazon is also reportedly prepping a second generation device of its Kindle Fire, following the success of its first generation tablet.
