Power performer: Apple
9.7" iPad, 1.4 lbs. (from $499, amazon.com)
Pros: The highest-rated overall for its display, speed, and video/camera/sound quality. Super-easy to use!
Cons: Thin but a tad heavy. Less customizable than Android. No physical keyboard or stand — not ideal for work.
Portable pick: Apple
Bing: iPad Mini
7.9" iPad Mini, 0.7 lbs. (from $329, amazon.com)
Pros: The second-best scorer, it fits in one hand. Thinner, lighter, but just as functional as the full-size version.
Cons: Screen resolution and camera/video quality aren't as sharp as the larger size's. Apps are a bit slower to open.
Power performer: Windows
Bing: Lenovo IdeaPad Yoga 13
13" Lenovo IdeaPad Yoga 13, 3.3 lbs. (from $999, amazon.com)
Pros: It's built like a laptop but, thanks to a unique 360-degree hinge, flips into a tablet. Does all a desktop can.
Cons: Windows 8 takes getting used to, said testers. Well suited for work (Word, Excel), but a bit hefty to carry.
Portable pick: Windows
Bing: Dell XPS 10
10" Dell XPS 10, 1.4 lbs. (from $399, amazon.com)
Pros: This convertible docks to a keyboard. Almost no lag time when swiping, zooming; great audio and camera.
Cons: Reviewers noted the keyboard made it heavier and deemed the screen's wide border unnecessary.
Power performer: Android
Bing: Sony Xperia Tablet Z
10" Sony Xperia Tablet Z, 1.1 lbs. (from $499, amazon.com)
Pros: The ultrathin tablet is water-resistant — safer from spills . Nice camera and picture resolution.
Cons: Sound quality wasn't tops; the absence of a physical Home button left many testers frustrated.
Portable pick: Android
Bing: Barnes & Noble Nook HD
7" Barnes & Noble Nook HD, 0.7 lbs. (from $199, bestbuy.com)
Pros: Not just for books, the Nook (also in 9") is a steal. Comfy to use, it has crisp images and responds quickly.
Cons: Lacks a camera and has limited processing power. Mainly for reading, e-mailing, and browsing.
