As soon as Apple rolled out the 15-inch MacBook Pro with Retina Display last summer, all the Mac addicts we know began clamoring for more Retina models, and this past fall Apple obliged, introducing a 13-inch version. From the outside, it looks just like its big brother: The same jaw-dropping LED-backlit display, with four times the pixels (2560x1600 in this case). The same advanced ports, including two Thunderbolt ports, two USB 3, HDMI, SDXC, and MagSafe 2. The same thinner, lighter design — this model just 0.75 inches thin (that’s a mere seven one-hundredths of an inch thicker than a MacBook Air) — and weighing only 3.57 pounds. But inside, it's pretty different.

Let’s be honest: the battery life of the iPhone 4 and iPhone 4S can kinda suck. Spyder’s PowerShadow i4 Battery Case & Charge/Sync Dock is designed to make it suck a whole lot less. Made out of black polycarbonate, the i4 boasts a built-in 2000mAh battery pack that, according to our testing, can charge a fully drained iPhone 4S to between 75 to 80 percent of its full capacity.

Duo Pinball aims to bring some of pinball's physical sensation back to the lap-based home experience, letting you affix a plastic dock to the back of any iPad — or less ideally, an iPhone or iPod touch — fire up a compatible app, and make use of the built-in plunger and side buttons for a seemingly more authentic feel. Powered by three AAA batteries and a Bluetooth link, the device pairs effortlessly and is easy to use, plus it'll hold your iPad snugly while you mash the deep blue flipper buttons — but the resulting sensation is less enthralling than expected.

The Compact Disc recently celebrated its 30th birthday, but for most people, digital files stored on a Mac (or streaming from a cloud) have completely replaced plastic discs shoved inside a stereo. But despite recent improvements to the speakers inside many late-model Macs, they're still lacking when it comes to listening to your favorite tunes. Palo Alto Audio’s Cubik is a pair of desktop speakers built to wring as much sound as possible out of your files, without hogging much space on your desk
