Not a bad start for Research In Motion’s BlackBerry PlayBook tablet according to Jeffries & Co. analyst Peter Misek. According to a recent research note, Misek estimates that the Canadian mobile giant sold 25,000 PlayBook tablets during the online pre-order period and another 20,000 on opening day. “If correct, 45K+ sell through on the first day would be a success,” wrote Misek. Although the figure doesn’t quite match the 300,000 original iPads moved by Apple on its opening day last year, the Economic Times notes that “the PlayBook’s first-day sales are much better than those of other tablets such as Samsung’s Galaxy Tab and Motorola’s Xoom.” RIM has yet to publicly comment on exact device sales figures.
