NOTHING COSTS MORE THAN IT USED TO:

Amazon.com Inc. kindled a price war in the tablet-computer market, unveiling a new slate of the devices that pack in more features at lower prices than Apple Inc.'s dominant iPad. . [...]

Mr. Bezos rubbed in the price contrast by debuting a $49.99 annual data package for the Kindle Fire that includes 250 megabytes per month. A similar data plan for the iPad starts at $14.99 a month, or about $180 a year.

That means consumers with a new 4G Kindle Fire will snag "more than $400 in year-one savings" versus an iPad, said Mr. Bezos.
