Sony VAIO model C1 subnotebook

A subnotebook is a small and lightweight portable computer, with most of the features of a standard notebook computer but smaller. The term is often applied to systems that run full versions of desktop operating systems such as Windows or Linux, rather than specialized software such as Maemo or Windows CE.

Subnotebooks are smaller than notebook computers but larger than handheld computers and ultraportables. They often have screens that are 10.4″ (diagonal) or less, and weigh less than 1 kg; as opposed to full-size laptops with 12″ or 15″ screens and weighing 2 kg or more. The savings in size and weight are usually achieved partly by omitting ports or having removable media/optical drives; subnotebooks are often paired with docking stations to compensate.

Subnotebooks are a niche IT product and rarely sell in large numbers.

History

1990

The Compaq LTE, launched in 1989, was the first to be widely known as a "notebook computer" because its relatively small dimensions—1.9 × 8.5 × 11 inches—were similar to an A4 paper notebook. The Compaq was followed by the very popular IBM ThinkPad, which was the first to include a 10.4 inch screen in a notebook measuring 2.2 × 8.3 × 11.7 inches. Portables with smaller form factors thus became known as subnotebooks. The term was also applied to the NEC UltraLite, unveiled in 1988, although its dimensions (1.4 × 8.3 × 11.75 inches) were very similar to the Compaq LTE.

Smaller DOS-based PCs such as the Poqet PC and the Atari Portfolio — both released in 1989 — were called either "pocket PCs" or handhelds.

1991–1995

One early subnotebook was the Gateway Handbook, originally released in 1992 and updated to use a 486 processor in late 1993. This computer was only 9.7 inches (246 mm) wide, 5.9 inches (150 mm) deep, and 1.6 inches (41 mm) high, and weighed less than three pounds (1.4 kg).

Another early subnotebook was the Hewlett-Packard OmniBook 300, which was launched as a "superportable" in 1993. It measured 1.4 × 6.4 × 11.1 inches, and was available with an optional Flash memory disk instead of a hard drive, to reduce the weight.[1]

Toshiba, which had concentrated on portables in the 1980s, also entered the market that year with the Portege T3400, claiming that "It's the first subnotebook computer with all the functionality of a much larger computer".[2] The version with an 8.4″ monochrome screen measured just 1.7 × 7.9 × 9.8 inches and weighed 1.8kg.

Then Toshiba really put the subnotebook PC format on the map in 1995 with the Libretto 20. This featured a 6.1″ screen and 270 MB hard disk. CNet reported about the Libretto 50CT that "[it] is the first full-fledged Windows 95 notebook in the United States weighing less than two pounds".[3]

1996–2000

In 1997, Apple launched the light-weight (4.4 lbs), but short-lived PowerBook 2400, which was co-designed by IBM and made for Apple by IBM Japan. However, this measured 1.9 × 10.5 × 10.5 inches, so it was actually bigger than a Compaq LTE notebook.

IBM had sold "thin and light" models in its ThinkPad range, such as the ThinkPad 560 ultraportable (1996) and best-selling ThinkPad 600 (1998). It finally entered the subnotebook market in 1999 with the ThinkPad 240, targeted at business travellers.[4] The 240 and 240X had 10.4″ screens. After the 240X, however, IBM concentrated on the "ultraportable" X range, with 12.1″ screens. At 1.1 × 8.3 × 10.6 inches, a system like the ThinkPad X40 only just qualifies as a subnotebook.

Sony launched an ultraportable less than an inch thick in Japan in 1997, the PCG-505, which reached the US in 1997 as the VAIO 505GX. This was followed by the even thinner Sony VAIO X505, which measured just 0.8 × 8.2 × 10.2 inches, and reached 0.3″ at its thinnest.[5] However, it was very expensive and had poor battery life, and was soon withdrawn.

Sony also launched the C1 range of subnotebooks, starting in Japan in January 2000.

2001–present

One of the most notable Sony models was the Transmeta-based Vaio PCG-C1VE or PictureBook (2001), which measured only 1 × 6 × 9.8 inches. It had a digital camera built into the lid, which could be used for video conferencing or swivelled round to photograph a scene.[6]

In 2006, Microsoft stimulated a new round of subnotebook development with the UMPC or Ultra-Mobile PC format code-named Origami. These are basically small versions of Tablet PC computers, which originally shipped with the Microsoft Windows XP Tablet PC Edition 2005.

Rumors in 2007 indicated that Apple could enter the subnotebook field. However, it seems more likely to produce a "thin and light" notebook, rather than a subnotebook.
