While not as lightweight as the original Kindle Oasis, the larger screen, more durable aluminum chassis and full waterproofing are important upgrades that put the new Oasis at the top of the e-reader class.
The Kindle Paperwhite gets an HD screen, and while it isn't as big an upgrade as you'd think, it's a welcome addition, incrementally enhancing the Kindle reading experience.
While the "all-new" Paperwhite may seem like an unspectacular upgrade on the surface, it's a clear improvement over the original Paperwhite and arguably the best e-reader currently available.
With an excellent built-in light and Amazon's best-in-class e-book selection, the Kindle Paperwhite rises to the top of the e-reader pack.
The Kindle Voyage is Amazon's best e-reader to date, and probably the best e-reader ever -- but it doesn't come cheap.
