Apple’s new iPad, which was launched with a bang continues to break tablet sales records in the US. However, reports indicate that the company’s previous model, the iPad 2 still stays popular in the U.S.

As per reports from Chitika that is based on data collected from its extensive ad network in the U.S., web traffic from the new iPad accounts for about 18 percent of all iPad traffic, while 60 percent still comes from the iPad 2. Chitika believes this to be a sign that people are still holding onto the old model of iPad. It points that the reason behind that sets in the minute differences between the iPad 2 and iPad 3 that is discouraging users of older iPads to upgrade.

Apple reportedly sold 17 million iPads this the past quarter, which is a record for the company. Apple CEO Tim Cook claims the new iPad is the most popular one sold ever. However, this data varies according to reports by Chitika. The reason can be Chitika talking about web traffic from iPads in the U.S. only, while Cook talking about sales in the global market.

iPad 2’s success can also be due to the discount that Apple offered, starting in March that reduced the cost $100 to $399.

Apple revealed that last week, between April and June this year, the company sold around 1 million iPads to schools. It has had a record-breaking quarter for Mac sales to schools, yet it sold twice as many iPads as it did Macs.

On the company’s earnings call with investors, Cook said pricing was a big part of the iPad 2′s success last quarter. Considering the sales of iPad 2, one fact is clear that Apple knows very well how to price products and make profits.
