Subnotebook
Subnotebook is the name for a very small and lightweight notebook. Common screen sizes ranging in these ultra-portable notebooks from 10.6 " (27 cm) 12.1 " ( 31 cm) to a maximum of 13.37 " (34 cm). Display sizes " are currently the most small computers, such as ultra mobile PCs ( UMPCs ) assigned greater from 14.1 " less than 10.6 (36 cm) notebooks most commonly occurring in the areas of office applications, multimedia and PC games. The weight of currently marketable devices is just under a up to a maximum of two kilograms. The equipment often comes close to a full-fledged laptop, but is not generally to optical drives and reduces the keyboard. Partial fewer connections are available.
There are exceptions, which are equipped with a full keyboard or with an optical drive, but then they are a bit heavier and / or larger.
The border with the keyboard also operated, but even smaller ultra-mobile PCs is fluid; In the past, served as a demarcation criterion - in addition to the display size and thus the form factor - often the presence of a full-fledged operating system, how it came into use even with desktop computers. Physically, both in size, weight as well as the computing power limits downward tablet PCs and smartphones. However, these are typically not AMD64 architecture, such as the sub-notebooks, constructed in but in ARM architecture.
Frequently subnotebooks are compared to standard notebooks with screen sizes of eg 14 "( 35.5 cm) or greater initially produced only in a small number of pieces due to the smaller sales market.
Disadvantages of these handy devices are the small screen (especially lower screen resolutions ), reduced keys with short stroke and partially - to save because of the size and Weight - small batteries, which reduce the runtime without connections to the grid full-fledged notebook. However, there are models where highly economical by combining processors and partly intentionally less powerful components is achieved a very long battery life, which is sometimes over 10 hours. The purchase price is significantly higher than that of a comparable standard notebook in many cases, either due to the compact design and the high running time.
History
To 1990
The Compaq LTE, published in 1989, was the first relatively well-known computer, the laptop computer was called, due to its relatively small size of 27.9 × 21.68 × 4.88 cm, which corresponds approximately to the size of an A4 page. After Compaq IBM launched the ThinkPad series, whose models used a 10.4 "screen and 297 × 21 × 5.6 cm were great. Smaller portable computer as these two were relatively quickly called subnotebook. The NEC UltraLite was published in 1988 and was 3.5 cm, for example, already named so due to its size of 29.8 × 21 ×. Smaller computer DOS-based, such as the Poqet PC and the Atari Portfolio, both released in 1989 were, however, called Pocket PC or handheld.
1991-1995
A 1992 published subnotebook, the Gateway Handbook ( 24.6 × 15.0 × 4.1 cm, 1.4 kg ), used a 486 processor in late 1993. In another subnotebook in 1993, the HP OmniBook 300, the standard built-in hard drive could be replaced with a surcharge of an optional solid state disk. The company Toshiba, which builds portable computers since 1980, launched its ultra-portable Portégé series in 1993 with the Portege T3400, which had a monochrome 8.4 "screen. The libretto was 20, however, was even smaller ( about the size of a VHS video cassette ) and had a 6.1 "screen with a hard drive capacity of 270 MB. Caused a stir in 1992 and the Quaderno, a full-fledged PC with MS- DOS in the format of today's netbooks.
1996-2000
Apple PowerBook 2400C with a 10.4 "screen brought out in 1997. This notebook was to replace IBM co-designed the old PowerBook Duo. After Apple introduced its subnotebook Seqment continued through the iBook G3 with 12 " monitor. IBM launched the ThinkPad 240 (1.3 kg), which was designed specifically for business, in the subnotebook market. This subnotebook has been replaced by the X - series of ThinkPads, which had a 12.1 "screen. 1996, 1997 and 1998, then appeared the libretto subnotebook series from Toshiba ( 210 x 165 x 33.4 mm). This series was continued again until 2005.
2001-2008
One of the most remarkable in today's market subnotebooks was on a Transmeta processor -based Vaio PCG -C1 VE, also called Picture Book, with a size of 24.9 × 15.4 × 2.5 cm Sony. The special feature of this model was then that a camera was mounted on the display lid, which can be found in many current laptops again. In 2001, before the Dell Latitude L400. The special feature of this notebook was the variable timing of the Intel CPU. In 2005, the Flybook was presented as a Tablet PC, which only had a 8.9 "screen. This subnotebook was available in many different colors and was even presented in non- PC magazines such as FHM, GQ, etc. The Samsung Q1 was a UMPC, which was a very small version of a Tablet PC and Windows XP Tablet PC Edition was operated in 2005.
In August 2007, Toshiba introduced the Portégé R500 ultraportable laptop with a full weighing less than 800 g before. The 12 "screen of this model there should also be in a flexible and pliable variant. In conjunction with a 64 GB solid- state drive (SSD ), this model can withstand heavy stresses and shocks. Apple introduced in January 2008 with the MacBook Air is an ultra portable subnotebook with a height of only 0.4 to 1.94 cm in front ( Dimensions: 32.5 × 22.7 × 1.94 cm, 1.36 kg). It has a 13.3 "display, a built-in battery, firmly integrated RAM and can also be ordered with a 64 GB solid- state drive. Of connections but only one USB port, a headphone jack and a mini -DVI port is available. The connectivity needs via WLAN, Bluetooth or a USB Ethernet adapter can be produced.
Since 2007 there is also the subclass of netbooks, where they are highly affordable and minimalistic subnotebooks. One example is the Eee PC, the Asus introduced in late 2007. On this computer the Xandros Linux distribution is installed, but it can also run with Windows. This netbook quickly led to the sales rankings of major Internet stores. However, it has a very small relative to the housing screen with 7 " and a resolution of 800 × 480 pixels.
The Chinese manufacturer Lenovo introduced in the spring of 2008, the Thinkpad x300, which is based on the technology acquired by IBM Thinkpad patents. It is only being shipped with a 64 GB solid- state drive, what the starting price greatly drives up, but also leads to improved running time on battery power as well as reduced vulnerability to physical stress. It clearly offers more connectivity options than, say, the Mac Book Air, and can by swapping the optical drive to achieve an extra battery with very long operating times.
In early 2008, some "middle class" subnotebooks came on the market that attempt to bridge the gap between the nearly -equipped netbooks and expensive high- end equipment. Here are more Eastern European brands such as the Polish manufacturer NTT and Aristo in tough competition with Asian manufacturers such as Asus.
Since 2008
In a time in which the Subnotebookmarkt expanding rapidly and the demand of special components rose rapidly (see Intel ULV CPUs), particularly Intel saw a chance to occupy the segment and has developed a special platform. The marketing name for this was " Ultrabook " (AMD moved to the "Ultra Thin" ). Special emphasis of marketing was the slim design and long battery life.
