Lenovo is updating the design of its ThinkPad laptops to keep them up-to-date in a market where computers are getting thinner and lighter at a fast rate.
The ThinkPad's external appearance isn't changing a great deal, but it is getting considerably thinner and lighter. The changes are exemplified in the new ThinkPad T431s, which will go on sale next month for US$949 in the U.S. and some other countries.
The T431s weighs 1.36 kilograms (3 pounds), or 24 percent less than the existing T430s, and it is 20.6 millimeters thick, or 21 percent thinner. It does away with the buttons around the touchpad and has a slightly thinner bezel around the display, and it comes in a lighter shade of black.
With the buttons gone, users now click on areas of a slightly enlarged touchpad to make selections and execute commands. The new ThinkPad still has the little red tracker button in the keyboard, as well as the other main features in existing ThinkPads.
"We don't change things all that often. We put in a lot of thought into all we did," said Alysia Baker, worldwide product marketing manager at Lenovo.
The bigger touchpad makes it more useful, according to Baker. That could be especially true with the release of Windows 8, which understands more types of gestures.
The ThinkPad remains the top brand for enterprises, according to IDC. Last year Lenovo shipped about 2.5 million ThinkPads to businesses with 1,000 or more employees, giving it 27.6 percent of the market, said David Daoud, a research director at IDC. That's up from 24.3 percent the year before.
The ThinkPad is keeping up with the times by getting thinner and lighter, but the inclusion of the red trackpoint button shows how IBM must cater to corporate ThinkPad users who may be resistant to change, he said.
Having to keep existing features makes life a bit harder for Lenovo. The trackpoint allows for precise navigation, which may be helpful for workers such as graphic designers or engineers, Daoud said.
"Many of these people have built a comfort zone and therefore a loyalty for this type of product," Daoud said. "It speaks of the nature of slow absorption of innovation in large corporate accounts."
Newer laptop features such as touch won't be adopted quickly by enterprises, and Lenovo has to evolve the ThinkPad to meet the specific requirements of IT departments, Daoud said.
"They don't want anything flashy, they want something that works," Daoud said.
Camellia Phillips, an avid ThinkPad user, has grown accustomed to using the buttons around the touchpad in conjunction with the red trackpoint button. She prefers the buttons to be visible rather than integrated with the touchpad.
"That's annoying. Why are they changing something that works so well?" Phillips said. She owns three ThinkPads and, like other ThinkPad users, appreciates the consistency and reliability of their design.
Lenovo also reduced the bezel area around the display in the T431s and put a 14-inch screen in what would otherwise be a frame for a 13-inch screen. The hinge is also more flexible and can tilt the panel through 180 degrees.
The changes will ultimately make their way to other T-series laptops, Baker said.
The ThinkPad went through a minor redesign with the ThinkPad X1 Carbon laptop, which was introduced late last year and included a new carbon fiber frame. That frame has been included in the T431s, though Baker was not sure whether it would be carried over to all other ThinkPads.
The T431s comes with an Intel Core i5 or i7 processor based on the Ivy Bridge microarchitecture. OS options include Windows 7 or Windows 8. The laptop can accommodate up to 12GB of DRAM and comes with a hard drive as big as 1TB or up to 256GB of solid-state storage. It also has a MiniDisplayPort, USB 3.0 and Ethernet ports.
The laptop provides nine hours of battery life, according to Lenovo's benchmarks. It has a webcam, and the display shows images at a resolution of 1600 x 900 pixels.
