TUAW posted a news story that consumer electronics shopping and review site Retrevo has conducted another study, this time about the iPad's rise in popularity

When asked, "What's preventing you from buying an iPad?", 52% of respondents answered, "I don't need one," and that's understandable. If you've got a functioning computer that you're happy with, or perhaps an iPod touch or an iPhone, there's no pressing need to buy an iPad.

The 2nd most common answer was, "Too expensive." Five hundred bucks is a decent amount of money for many people, especially those who already own a laptop or iPod. However, those with modest computing needs looking for a machine will find the iPad much less expensive than even an entry-level MacBook (although it's comparable to, or pricier than, a netbook).
