Computer types: There are hundreds of manufacturers and vendors offering plenty of different products. But we can basically focus on several types of computers for different uses.
Personal Digital Assistant (PDA) or handheld
computers:
These are very small computers with limited functionality. The
general function of such computers is organizing. Many
people find them incredibly handy and run them in different
circumstances and locations. Popular examples would be Palm
Pilot, the Psion Organizer, Compaq Aero, and so on. Some actually run
a compatible version of Windows so that you can swap files with your
normal size computer. These devices have some basic features:
Date book to input the time of meetings, appointments, etc.
Memo Pad to place notes and write whatever.
Calculator to solve problems via calculations.
To-Do List to help accomplish some tasks.
Address Book to keeps track of all your important contacts.
OnScreen Keyboard to let typing with the touch screen and your stylus.
Grafitti (Palm)/Character Recognizer (Pocket PC) to let handwriting on the screen instead of typing on keyboard.
Email option to let composing and sending email.
Note: Graffiti is the trade name for the specialized set of characters that the Palm recognizes.
There is also a lot of entertainment value in the PDA. You can find many games to please any taste, and. use software to carry your pictures, listen to music, watch a movie, etc. Major manufacturers are Sony, Handspring, Palm, Hewlet-Packard, Casio, Compaq, Toshiba, Handera, ViewSonic.
Ultra personal computer (uPC):
The OQO issued the model 01 of uPC
as a fully-functional
Windows XP computer. OQO model 2+ has Intel Atom Performance, 2GB of RAM,
OLED display. The OQO Docking station allows connection to a full size
display, keyboard, mouse, and so on. This type of computer is powerful enough to run most
complex applications at work, sending email at home, listening to
music on a train, or watching a movie on an airplane.
A new generation of minicomputers differs from minicomputers, which was developed in the last Century by Digital Equipment Corporation (DEC), Hewlett-Packard, Honeywell, and others. In size and power modern minicomputers lie between microcomputers and normal PC or workstation (desktop or laptop).
Netbooks. Netbook is a small portable computer, designed mainly for easy network connectivity including Internet access in any places. Netbooks need low power, are low weight , small size and low cost. For example, Dell issued Mini 10 and Mini 10v Netbooks with a keyboard 92% the size of a traditional laptop keyboard, wireless options, build-in GPS , et cetera. Now netbooks can be found from most major retailers for price less than $300.
Mini Book PC, Book PC, Cube PC (Shuttle) and others , developed by TheBookPC.com, Inc. are space saving minicomputers with performances like some traditional larger desktop computers.
Little PC computers , developed by the LittlePC, Inc (a division of Stealth Computer Inc. (www.stealthcomputer.com)) available on the Market in the different configuration .
Portable computers (Laptops,
Notebooks): Usually these are very powerful little boxes no bigger than a small
briefcase. Now it is difficult to say what is better: a portable or a stationary computer.
Comparison of both types demonstrates that by functionality,
the stationary and the portable computers have approximately the
same useful scores.. Quickly find out what your needs are here.

Communicators and other combined devices:
The Treo 300 communicator (Handspring, Inc.)
integrates a color Palm OS® organizer, keyboard and mobile phone into a
versatile productivity tool. Sony's NZ90 is quite an amazing
achievement, integrating their hot 200MHz Palm OS-based PDA
with a 2.0 megapixel digital camera that can capture stills or video; it even has a flash.
iPad: The iPad is a tablet computer designed and
developed by Apple. It is particularly marketed for consumption of media such
as books and periodicals, movies, music, and games, and for general web and
e-mail access. Its size and weight are intermediate between most contemporary smartphones and laptop computers.
iPhone:
The iPhone comprises a camera phone, including text messaging and visual
voicemail, a portable media player, and an Internet client, with e-mail, web
browsing, and Wi-Fi connectivity. The user interface is built around the
device's multi-touch screen, including a virtual keyboard rather than a physical
one.
Tablet PC: Tablet PC is a new step of development of portable computers. While tablet PCs have appeared in various forms for more than a decade ago, they've never really caught on with consumers. But the recent introduction of a special version of Windows XP has re-energized the concept. Several companies, including Hewlett-Packard/Compaq, ViewSonic, Toshiba and Fujitsu, created new tablet PCs. These PCs are more versatile than a laptops and more powerful than a PDA. You can switch screen from a horizontal view to a vertical one, hold the tablet PC on your lap while you write notes on the screen or peck out words on its virtual keyboard with a digital pen.

Stationary
computers (Desktop, Tower, Mini Tower and so on): Desktop means exactly that: a machine that
is designed to sit on or under your desk. Tower, Midi, or Mini Tower are variations of these with
more room for expansion. Stationary computers can be very convenient in business or at home,
and they are by far the best selling type of PCs in the world today.

Workstations: Generally a workstation has the same functions as the stationary computers, but the term tends to be reserved for more powerful versions. Many components and functions that are typically found on desktop computers today, were once technologies reserved for the high-end workstation market or servers in the past.
Servers:
If the above mentioned types are personal computers for personal use, servers are not
personal computers. These are machines that sit on a network, and execute the special functions of
the network, for example, acting as a central storage and processing area for files, printers and
communications between computer users.
Special computers. Now we observe the beginning of the new trend . Some manufactures (for example, Gateway with series DX, LX and FX) issued computers for entertainment and for gaming. Some Gateway computers can be customized as the ultimate photo computer, the movie PC , and so on.
All-in-one-computer.
Some manufacturers designed all-in-one-PC inside a monitor
for multiple markets: health care, banking, education, goverment, and other
industries. Product line can include all-in-one-computer in an LCD
monitor, in a keyboard, and medical grade all-in-one PCs that can be used in
sterile environment.
The
iPod family. The iPod came from Apple's digital hub strategy, and
designed on the base of computer technology. Devices in the iPod family are
designed around a central scroll wheel (except for the iPod shuffle) and the
full-sized model stores media on an internal hard drive, while the smaller iPod
nano and iPod shuffle use flash memory. Like many digital audio players, iPods
can also serve as external data storage devices.
Apple computer Inc. released several models : iPod with a video player; the aluminum iPod nano with a color screen; and the iPod shuffle, iPod touch.
Before you make the final decision about the type of computer, you need also to look on your future computer from the point of view of you health.
Health point of view for your choosing a computer:
In terms of workplace ergonomics, the general rule of use of any device with a minimal risk for health is a comfort for user. As is known, intensive and prolonged a computer usage (more than 3 hours per day) without comfort ( wrong type of monitor, bad input devices, bad chair, wrong position of monitor or posture of user, and so on) can lead to health risks such as Repetitive Stress Injury, which include Tendonitis and Carpal Tunnel Syndrome, Eyestrain, Lower back pain, Muscle fatigue and Emotional fatigue. Therefore if you ignore these ergonomic problems, you can have trouble with your new computer, especially if you select a portable computer for permanent use in the working place.
Portable computers were originally designed as a temporary solution - a short-term replacement of desktop PC for travel needs. But as they improved, laptops and notebooks became for many people the primary (and sometimes the only) computers. Portable computers are now a staple of business and educational computing. Unfortunately, in this field, most products are designed without user safety in mind. These is what you can do to protect yourself or your children. First approach, is either don't use a portable computer for permanent job , or use it with special accessories such as docking stations, external mice, external keyboard, glare filters, detachable screen, and so on. Theses accessories help you to diminish a risk of computer users diseases. For more information see HealthyComputing.com's guide.
