On April 3, 2010, America penned a massive love letter to Steve Jobs. Or to magic and revolution, whichever you prefer. How’s this for brand loyalty? 74 percent of Saturday’s iPad buyers in Minneapolis and New York were Mac

users, and 66 percent owned an iPhone, according to Piper Jaffray. There hasn’t been this high a concentration of fanboys since the launch of the first iPhone in June 2007.

Ninety-two percent of the iPad buyers surveyed by Piper Jaffray owned an iPod. Of the 13 percent who owned Amazon Kindles, 58 planned on using the iPad as a replacement device.

Chitika came at the numbers a bit differently, measuring the traffic coming from iPads, but still had some interesting findings, like the fact that nearly one fifth of iPad users were in California. As of this writing, Chitika estimates that there had been 301,709 iPads sold. (At 3:00 p.m. PST, they were selling at the rate of 81 per minute.)

According to Apple, 300,000 iPads were sold on Saturday, and more than 1 million iPad apps were downloaded that day. An average of over three app downloads portends well for the future of tablet apps.

Silicon Alley Insider reports that the iPad is already outselling competitors . . . in the smartphone market. Apple has already sold more iPads than Palm sold Pres last quarter, which portends not well for Palm’s premiere smartphone. As does the fact that Apple’s tablet already has a much richer app ecosystem.
