Apple announced that it's replacing its iPad 2 with a higher-resolution Retina display iPad, and it may not be long until the lower-resolution screen is nixed altogether.
"I would not be surprised if that was gone by the end of the year," said Dan Ackerman, a senior editor at CNET.
The iPad 2 replacement will be a 16-gigabyte, 9.7-inch Retina display iPad starting at $399, the same price as the iPad Mini with a Retina display. The larger of the two was initially launched as the fourth-generation iPad with a $499 price tag.

Apple is also trying to get consumers to use Apple devices that have the same power cords, according to Ackerman.
"They're really trying to get everyone on to the new, smaller Lightning connector. ... The sooner you can standardize, the easier it is to sell accessories and add-ons," Ackerman said.
