They’re Hot for the 3G iPad…49 of 50 Stores Sold Out Over the Weekend

Fortune Magazine reports: Piper Jaffray’s Gene Munster, one of the few Apple (AAPL) analysts who attends product launches and counts heads, estimates that Apple sold 300,000 iPad 3Gs over the three-day launch weekend, including units pre-ordered online for Friday delivery. That’s the same number of units Apple sold in one day when the Wi-Fi-only model launched.

The lines at the stores Munster and his crew monitored — Apple’s Fifth Ave. store in New York City and a mall store outside Minneapolis — were shorter than those for the initial iPad launch on April 3 (329 vs. 730 and 119 vs. 132, respectively).

But given that customers had two and a half days to buy iPad 3Gs (versus one for the Wi-Fi model) and twice as long to put in pre-orders, Munster figures 300,000 sounds about right.
