Which Lenovo series is known for being thin and light?

The T series within Lenovo's portfolio is indeed well-known for its thin and light design, making it popular among professionals who prioritize portability without compromising performance. The T series exemplifies Lenovo’s commitment to combining lightweight designs with robust hardware and features suitable for business and productivity tasks.

In the context of the broader lineup, while the ThinkPad may also include models that are thin and light, the T series is specifically recognized for this characteristic due to its design philosophy and target audience, which includes frequent travelers and business users. Models within the ThinkPad family vary greatly, but the T series stands out with its consistent focus on providing a balance of mobility and power.

Though the Idea series caters more toward casual users and offers a range of device types, its primary focus is not on the thin and light category but rather on providing budget-friendly options for home and entertainment use. The Legion series, on the other hand, targets gamers and performance enthusiasts, emphasizing powerful graphics and processing capabilities over a lightweight form factor, thus usually resulting in bulkier designs.

Therefore, the T series aligns best with the criteria of being thin and light, making it the appropriate choice in this context.
