The laptop as we know it is in the middle of an identity crisis.

After years of solid growth without any fundamental changes—aside from a quick, ill-fated flirtation with netbooks—the clamshell's relevance is now threatened by phones and tablets. The new breed of touchscreen mobile devices hasn't eliminated the need for PCs with trackpads and keyboards, but they have caused people to rethink whether they need a second notebook at home.

In response, PC makers are now ushering the laptop into the era of touch, with help from the drastic operating system overhaul that is Windows 8. The ride will be bumpy over the next few years, as PC makers try to generate excitement for laptops by introducing new hybrid designs, such as swiveling touchscreens and detachable displays.

But what happens after that? In five years, once the transitional hybrid period shakes out, what will the clamshell look like?

PCWorld spoke with chip makers, PC manufacturers, and analysts to learn more about what laptops will offer circa 2018. Join us as we peer into a multifaceted crystal ball to decipher the future of the notebook.

Refining the hybrid

As PC manufacturers ready the first round of Windows 8 laptop-tablet hybrids, they're willing to admit that their concepts are works in progress. Over time, they'll need to eliminate clumsy hardware compromises in the conversion from clamshell to tablet (and back again), such as awkward twisting motions, and the need to use two hands to detach a hybrid's display from its keyboard.

“Clearly, the ecosystem hasn't gotten [hybrids] right yet,” says Kevin Lensing, AMD's director of notebook products. “They're interesting, but maybe a little bit hokey in their implementation.”

Employing a swiveling screen design, Dell's XPS Duo 12 is a Windows 8 hybrid that doesn't immediately inspire build-quality confidence.

Lensing says that he's already seen some of the next-generation laptop-tablet hybrids from PC vendors, and their conversion mechanisms already look and behave better than those of the first wave of products. Some even gain processing power when the tablet is docked to a keyboard and trackpad.

Over time, Lensing expects docking to become more seamless, even as it adds power, storage, and extended battery. “We're in year one of a brand new mechanical design, and I think there's going to be multiple iterations of getting it to be just as robust as a real notebook,” he says.

Mark VandenBrink, chief technical officer of HP's PC business, agrees that the next five years of hardware development will focus on reducing the clunkiness of the laptop-tablet hybrid. HP is no stranger to the category—the company's TouchSmart laptops appeared before Windows 8, and VandenBrink expects to see both good and bad designs as PC makers adjust.

“It's easy to do, but it's really, really hard to do well,” VandenBrink says.

Even as convertibles begin their long process of evolution, there's still room for a major shake-up. Pat Moorhead, a tech industry analyst and consultant who specializes in future scenarios, believes that the modular PC concept will eventually go wireless. Smartphones could one day provide all the necessary storage and processing power, and the laptop may become little more than a dumb shell.

The software barriers to making this happen are already falling, Moorhead says, with operating systems such as Android and iOS designed to scale across screen sizes. He thinks that roadblocks in wireless technology could be demolished within five years as well.

The WiGig Alliance is already pushing for the use of spectrum around 60GHz, which would support speedy display connections and wireless docking. The challenge, Moorhead says, will be to get device makers to agree on a standard for wireless communication among devices.

But he's optimistic. “With the proliferation of very inexpensive large displays, it's going to be hard to walk into a room in the western world where you're not going to be able to connect to some sort of display,” Moorhead says.

Moving beyond the trackpad and keyboard

The keyboard and trackpad aren't going away, at least not on the watch of the PC manufacturers I spoke with. But those old standbys may evolve in the next five years to grow alongside new input methods.

Mark Aevermann, a senior product manager at Nvidia, thinks that voice recognition, hand gestures, and even eye tracking could take off in the next five years. Relevant concepts are already kicking around now—Apple's Siri, Microsoft's Kinect, and Tobii's eye-tracking technology come to mind—and though they may now seem ill-equipped to supplant trackpads and keyboards, Aevermann recommends keeping an open mind.

“I think writing off any one device category or method of input or interaction is basically saying there aren't creative people out there,” he says. “I think there are tons of people out there thinking about how to make the experiences more accessible.”

As for the trackpad, HP's Mark VandenBrink sees room for improvement in a couple areas. Instead of trackpads consisting of a tiny square in front of the keyboard, VandenBrink envisions a dynamic trackpad that covers a lot more of the laptop's surface. He also sees potential for adaptive trackpads that learn your preferences and tendencies as you go.

Synaptics' pressure-sensitive trackpad alludes to future innovation in all touch design.

We're already starting to see some innovation on the trackpad and keyboard front. Last month, Synaptics introduced a pressure-sensitive trackpad and a capacitive keyboard that is thinner and lets the user disable the cursor while typing. The trackpad on Intel's Nikiski concept, shown off at CES in January and pictured at the very top of this article, runs the length of the keyboard and uses palm detection to switch off during typing.

Moorhead offers some other far-out ideas for overhauling the trackpad and keyboard completely. Notebooks of the future, he imagines, could come equipped with two or more high-definition cameras, working in concert to track the user's hands. If the cameras become accurate enough, they could allow any surface to serve as a trackpad, as the cameras pick up the gliding of your hand and the twitching of your fingers, and the laptop's software translates that information into cursor functions.

The same possibility applies to keyboards. Moorhead believes that, with high-definition cameras on either side of the screen, any surface could become a virtual keyboard, with the screen showing a virtual keyboard overlay indicating where the user's fingers are landing.

Users may at first resist the idea of losing physical feedback from a trackpad, but Moorhead notes that the iPhone's touchscreen keyboard was pooh-poohed in its early days as well.

“The reality is you give [people] an alternative where there's a benefit, and you could potentially eliminate the entire keyboard deck,” Moorhead says. He admitted, though, that this scenario is unlikely to become reality in the next five years.
