Apple on Tuesday raised the curtain on its next-generation iPhone X, and it so far has been greeted with praise -- though tentative -- from early hands-on reviewers. For the most part, they gave the X kudos for design and build, but reserved their unequivocal endorsements until they could spend more time with the phone. A sore point with many reviewers was the mobile's price. A unit with 64 gigabytes of storage costs $999 and one with 256 GB costs $1,146. Not all reviewers were annoyed by the pricing, though.
