The lines for yesterday's initial sales of the iPad 2 were widely predicted to be shorter than at launch last April. In fact, they were longer. Over 1,110 people were lined up at the Apple Store on Fifth Avenue in New York, compared to 730 at launch. It's now expected that Apple could sell as many as 500,000 iPad 2s the first day, compared to 300,000 the first day last April. And Bloomberg is predicting sales of 600,000 units this weekend. Many stores sold out. And a survey of 250 people in line at one store found that 70% of them already owned the original iPad. Clearly the iPad is popular, and getting more so. The competition at this point doesn't seem much of a threat, given that they're unable to match Apple's pricing.
