Mobile ad network Mobclix surveyed 50 of the 250 customers waiting in line at Apple's Palo Alto retail store. According to the survey, 70 percent of respondents were upgrading from the original iPad.
It should be noted, however, the results should be taken with a grain of salt, as Silicon Valley residents are likely skewed toward early adopters.
20 percent of those surveyed indicated they would purchase a 3G-capable iPad 2. Customers favored the AT&T network, with 68 percent planning to purchase the AT&T iPad 2 and 32 percent planning to buy the Verizon model.
The survey also found that the top three new features users are excited about are the device's cameras, faster speed and FaceTime video chat.
The Palo Alto Apple Store has historically been a busy site on product launch days, as it is located just 20 minutes from Apple's campus in Cupertino. Last April, Apple CEO Steve Jobs made an appearance at the store for the launch of the original iPad.
For its part, Apple is hoping for lightning to strike twice with the iPad. During the media event announcing the second-generation tablet, Apple declared 2010 the "Year of the iPad," before pronouncing 2011 the "Year of the iPad 2."
Jobs also highlighted the iPad as Apple's "third post-PC blockbuster product." Following the launch of the original iPad last year, Jobs hailed the tablet as the leader of an "uncomfortable" transition to the post-PC era.
Early indicators suggest Apple does have another hit on its hands. Checks to several Apple Stores by Piper Jaffray analyst Gene Munster revealed that lines were, on average, 104 percent longer than last year's launch, with over a thousand prospective buyers in line at the 5th Avenue Apple Store in New York.
Munster predicts that Apple could sell as many as 400,000-500,000 units of the iPad 2 in its first day of availability. According to one analyst, Apple could sell as many as 1 million units in the first weekend of iPad 2 sales.
