Traditionally black, ThinkPads feature innovations such as:
Magnesium, carbon fiber reinforced plastic or titanium composite cases
TrackPoint pointing device
ThinkLight, an LED keyboard light at the top of the LCD screen
Solidly constructed full-size keyboard
Active Protection System, an accelerometer sensor which detects when a ThinkPad is falling and shuts the hard drive down to prevent damage
Roll-cage design to eliminate motherboard flex and drain holes on keyboard to reduce damages from an accidental spill
Biometric fingerprint reader
Client Security Solution, which improves security using a built-in TPM and facilitates deployment in corporate environment
ThinkPad Design history
In 1992, IBM introduced the first ThinkPads, 700 and 700C, into the market.[1] The 700C, with Microsoft Windows 3.1 operating system, 25 MHz 486SLC processor, 120 MB hard disk drive, the industry's first 10.4" TFT color display,[1] 2.2" x 11.7" x 8.3" dimension (56 x 297 x 210 mm), and 3 kg (6.5 lb) weight, cost US$ 4,350. The design of the commercial versions differed significantly from the prototype's keyboard-less tablet design. The bright red TrackPoint, embedded in the keyboard, enabled the notebook to be used on an airline tray table without a mouse. An IBM researcher conceived the title "ThinkPad" from a corporate-issued leather-bound pocket notebook with the corporate motto 'Think' embossed on the cover.[1] The name met disagreements from the IBM corporate naming committee because the nomenclature system for the IBM computers was then numerical; however, the brand name "ThinkPad" was kept as the press showed appreciation for the title.[2]
ThinkPads have been praised for exceptional build quality, system reliability, and services throughout their decade and a half of presence in the consumer market.
Tom Hardy, corporate manager of the IBM Design Program met Italian-based designer Richard Sapper (noted then for the design of the Tizio lamp and later commissioned to design a ballpoint for Lamy) and Kazuhiko Yamazaki, lead notebook designer at IBM's Yamato Design Center in Japan. Sapper proposed a design inspired by the Shōkadō bentō, a traditional black-lacquered Japanese lunch box.[1]
The fold-out butterfly keyboard, which appeared in the ThinkPad 701 series, is widely considered a design masterpiece and is on display at the Museum of Modern Art in New York. Another interesting design was in the Thinkpad 760 series, where the keyboard was elevated by two arms riding on small rails on the side of the screen, thus creating a more ergonomic, tilted keyboard as opposed to the flat keyboards of other laptops.

ThinkPad 235
Type 2607, or the Japan-only ThinkPad 235, is an interesting product because it is a progeny of the IBM/Ricoh RIOS project. Also known as Clavius or Chandra2, it contains unusual features like the presence of 3 PCMCIA slots and the use of dual camcorder batteries as a source of power. Features an Intel Pentium MMX 233 MHz CPU, support for up to 160 MB of EDO memory, and a built-in 2.5 inch hard drive with UDMA support. Hitachi markets Chandra2 as the Prius Note 210.
ThinkPad 240
The ultraportable ThinkPad 240 (X, Z) started with an Intel Celeron and went up to the 600 MHz Intel Pentium III. The RAM was expandable to 192 MB max. With a 10.4 inch screen and an 18mm key pitch (A standard key pitch is 19mm). They were also one of the first Thinkpad series to contain a built-in Mini PCI card slot (form factor 3b). The 240s have no optical drives and an external floppy drive. An optional extended battery sticks out the bottom like a bar and props up the back of the notebook. Weighing in at 2.9 pounds (1.3 kg) these were the smallest and lightest ThinkPads ever made.
ThinkPad 300 series
The 300 series (300, 310, 340, 350, 360, 365, 380, 385, 390 (all with various sub-series)) was a long-running value series starting at the 386SL/25 all the way to the Pentium III 450. They were a bit large and slower than the more full-featured models but offered a less expensive ThinkPad.
ThinkPad 500 series
The 500 series (500, 510, 560 (E, X, Z), 570 (E)) were the main line of the ultraportable ThinkPads. Starting with the 486SX2-50 Blue Lightning to the Pentium III 500, these machines had only a hard disk onboard. Any other drives were external (or in the 570's case in the ultrabase). They weighed in at around 4 pounds (1.8 kg) and because of their excellent design are still in use today.
