NEW YORK (AP) — A report this week in The Wall Street Journal that Amazon is planning to release a smartphone has prompted industry analysts and technology blogs to muse about what the device might offer.

Amazon hasn’t confirmed that it has plans for a smartphone. Introducing such a device would be tough in a crowded market dominated by Apple and Samsung. Even so, innovations like the Kindle Fire and Prime membership program demonstrate that the online retailing giant has a knack for using its massive size and marketing budget to capitalize on gaps in the marketplace.
