18.00": This display size is a standard format for desktop replacements (DTR). The DTR laptops are heavier to carry, need more power, but texts are easy to read and high resolutions are no problem. DTR are mainly intended for stationary desk use, where weight and energy hunger don't matter. In return, you enjoy the advantages of high resolutions (more details, better legibility).» To find out how fine a display is, see our DPI List.


3.5 kg:

A laptop with this weight is comparatively heavy and less designed for mobility than for use at the desk. Therefore, the devices tend to shine less with battery life than with a large screen and higher performance.


Lenovo: Lenovo ("Le" from English legend, novo (Latin) for new) was founded in 1984 as a Chinese computer trading company. As of 2004, the company was the largest laptop manufacturer in China and, after acquiring IBM's PC division in 2005, the fourth largest in the world. In addition to desktops and notebooks, the company manufactures monitors, projectors, servers, etc, and specializes in developing, manufacturing and marketing consumer electronics, personal computers, software, enterprise solutions and related services.

In 2016, the company ranked first in the world in computer sales. It still held it in 2023 with about 23% global market share. Important product lines are Thinkpad, Legion and Ideapad.

In 2011, it acquired a majority stake in Medion AG, a European computer hardware manufacturer. In 2014, Motorola Mobility was purchased, which gave Lenovo a boost in the smartphone market.
