Research In Motion will finally launch its anticipated BlackBerry PlayBook tablet on April 19th, though most had initially expected it to reach consumers well before that date. According to a new report from DigiTimes, Apple may have been behind the rumored delays. The report states that RIM’s touch panel supplier, Foxlink, was so inundated with display orders from Apple that it wasn’t able to meet RIM’s manufacturing needs on time. “Sources from touch screen panel makers also pointed out that PlayBook shipments were postponed for about a month from the original schedule due to a delay in software testing as well as shortage of touch panels because Apple already booked up most of the available capacity,” the report claims. RIM’s late launch could have a significant impact on PlayBook sales, though several analysts believe the BlackBerry tablet will still sell quite well in its debut year.
