The report shows that 13 percent of owners purchased the iPad iPad instead of a PC. An additional 24 percent have bought an iPad rather than an e-reader. For me it works Thirteen per cent in a significant number of consumers not to buy a PC for IPAD.

NPD said that consumers that purchased an iPad within two months of its launch are more likely to own Apple products and newer technology. That makes perfect sense for a new product like the iPad.

In fact, 50 percent of initial buyers owned a Mac and 38 percent also owned an iPhone, according to the report.

Stephen Baker, Vice President of Industry Analysis for NPD said that 80 percent of early adopters (those purchasing within two months of the launch) were satisfied with the iPad. That number dropped to 65 percent after the initial two month period.

On the list of things consumers didn’t like about the iPad were the lack of multitasking and not having an easy way to print. Both of these items will be addressed in iOS 4.2, which is expected to be released in November.

DisplaySearch has released a report Thursday that showed that shipments iPad not, the netbook category has declined from 14 percent in the second quarter and 13 percent rate.
