Crux360 iPad 2 Keyboard


Aluminum Keyboard Buddy Case cloaks your iPad 2 in a MacBook Air duvetCrux Loaded case almost turns your iPad into a laptop for $250MacBook Air review (mid 2011)Yeah... we know. At this point you're probably clutching your funds tightly, eagerly...

Excellent connectivity ; Full hinge rotation ; iOS function keys

Cramped keyboard ; Doesn't fully cover the iPad ; Pricey

The Crux360 offers a 360-degree hinge and convenient iOS keys, but the cramped keys and lack of full iPad protection give us pause.

Deck 82 keyboard (Ice Blue) review


IBM made its first Model M keyboard in the 1980s, and it quickly rose to a cult product among typing purists who preferred its buckling spring keys to the thin scissor-switch laptop keys we use today. The Deck 82 is the latest iteration of the classic...

The backlit, compact 82-key layout helps the Deck 82 keyboard fit in tight spaces, and its affordable price tag makes it an excellent mechanical keyboard for first-time adopters and mod-freaks alike.

The keyboard lacks an integrated palm rest, which may limit its appeal for heavy typists.

The Deck 82 keyboard's space-saving design, adjustable backlit luminescence, and low price tag make this fully customizable keyboard a win for mechanical keyboard typists.

Smartfish Engage Keyboard


The Smartfish Engage ergonomic keyboard is an interesting concept, but it fails a the most basic keyboard function—the typing experience.

Plug-and-play capabilities. Numeric keypad. Keyboard dynamically adjusts to alter your typing experience

Keys are a bit stiff. No media function keys. Noisy motor when adjusting keyboard

Challenger Gaming Keyboard Pro


Component maker Thermaltake's foray into enthusiast peripherals is a somewhat mixed bag with the Challenger Gaming Keyboard Pro, a robust midrange gaming keyboard that will meet the needs of almost everyone except typists.

High customizability via both software and hardware. Powerful, intuitive driver software. Carrying cases included for all major components

Function key row can interfere with game play. Certain design elements make typing a chore. No Mute key. Detachable cooling fan is underpowered

The Earthquake Keyboard


With its three keypad units, the Comfort Keyboard looks more like the victim of a tremor than an input device. One divide separates the main keymap into two units (similar to a split keyboard), and the second frees the number pad. A metal base joins...

Game-Customized Keyboard


PC gamers know the frustration of having to memorize a dozen hotkeys or trying to use an odd-shaped keyboard-replacement controller. The Ideazon Zboard offers game-specialized overlay boards that fit onto a generic keyboard casing. Each overlay is...

Smartfish Engage Compact Keyboard with ErgoMotion


Black plastic encases the Engage, matte for the keys and a glossy finish for the palm rest. The glossy portion did tend to attract smudges and fingerprints over time. At its largest points the Engage measures about 2 by 20 by 7.5 inches (HWD) and...

Padacs Rubata Keyboard


This accessory is the best iPad keyboard/case combo yet, but it's far from perfect.

Stylish design ; Large, responsive keys ; Helpful shortcut buttons

Heavy ; Misplaced keys ; Can't use on lap

Among the three iPad keyboard cases we've reviewed thus far, the Padacs Rubata is the one we prefer. The soft exterior combined with the crisp key feel makes for a pretty comfortable typing experience. Still, there's plenty of room for improvement. You...

Review: The Cool Leaf buttonless keyboard


We live in a world of touchscreens. For the most part, those touchscreens are dedicated devices that react to a tactile response. Completely buttonless, these devices are paired with software and exist both as the next wave of technology and as a...
