The hard disk space offered was a 32 GB-high for the time. The 14.1-inch LCD display offered a higher resolution of 1400 × 1050. In October 2000, the ThinkPad T20 was upgraded and released as the ThinkPad T21 laptop with the Intel Mobile Pentium III (800 MHz) CPU. With the addition of an internal 8x DVD-ROM drive, the weight remained as low as 2.4 kg (5.2 lb). With a weight of 2.1 kg (4.6 lb), the T20 was the lightest laptop offering with a screen size of 14.1-inch (360 mm). The ThinkPad T20 was released by IBM as the 14.1-inch successor to the 13.3-inch ThinkPad 600 laptops. Users were also given options to swap components for mobility, like a DVD player, writeable CD drive or numeric keypads. Despite a 14.1-inch screen, similar to desktops at the time, the titanium composite body on the laptop was designed to keep the weight as low as possible. įrom the time of its inception, the series was designed to balance speed and mobility. This resulted in the development of the IBM Embedded Security Subsystem. The laptop was meant to cater to users working with multiple networks and in different environments.

IBM introduced the T series as part of their ThinkPad brand in 2000.
