A small but sizeable fraction of iPad buyers on launch day were doing so to replace the Amazon Kindle, analyst Gene Munster at Piper Jaffray said today. Based on 448 interviews at Apple stores in New York City and Minneapolis, about 13 percent of iPad buyers already own a Kindle and just over half of those, or 7.5 percent of the total, were planning to replace Amazon's e-reader with Apple's. Exactly 10 percent had considered getting a Kindle but decided on an iPad instead.
