Introducing the Tablet PC
The Tablet PC is a notebook or slate-shaped mobile computer that
is approximately the size of a paper tablet. It gives us
portability, flexibility and usability that are changing the way
we work with our computers. Its touch screen or digitizing
tablet technology allows the user to operate the computer with a
stylus or digital pen instead of a keyboard or mouse.
Tablet PCs will have two formats: the "convertible" model with
an integrated keyboard and a display that rotates 180 degrees
and can be folded down over the keyboard, and the "slate" model
with only a screen and pen. They can use external wireless or
USB keyboards. The most popular convertible tablet PCs are the
Acer and Toshiba. The most popular slates are the Motion
Computing/Gateway Computers, Fujitsu, and HP/Compaq.
Many Tablet PCs use a Wacom digitizer, which delivers
pen-position input to the computer at a fast rate. Tablets with
these digitizers project a small magnetic field above the screen
that interacts with electronics in the tablet's stylus. The user
therefore is able to rest their hand on the screen without
affecting the image or mouse pointer; only movement of the
stylus affects the mouse pointer.
Tablet PCs became available to the general public with the
introduction of Microsoft's Windows Tablet PC Edition in the
fall of 2002. Before then they were used in small markets in
industry, medicine, and government. Now they are used by
students and many professionals.
Let us now have a look at the improvements in Tablet PCs:
The battery life of Tablet PCs has increased a great deal. This
gives us more freedom to do hat we need to do when we need to do
it. We're free to take our computers into meetings and
classrooms and to take notes the way that's most familiar, by
writing. Centrino technology has improved. This means that more
powerful processors can be used with little or no loss of
battery life compared to lower powered CPUs.
Better wireless support allows us to log on to networks more
easily than ever, with built in firewire. All this convenience
comes packaged in a 3 pound computer that's not much bigger than
a paper tablet.
Those who don't type have the option to use handwriting, can use
keyboard to enter data. Others may prefer speech input, or a
combination of both. We're free to take our computers into
meetings and classrooms and to take notes the way that's most
familiar, by writing.\
Tablet PCs are lighter than the majority of notebooks. Most
weigh about 3 pounds or less. Size is also smaller, with the
Tablet PC about the size of a paper tablet. Some of the newer
Tablets have larger screen sizes or built-in drives. These can
increase the weight considerably.
The Tablet PC uses a low or ultra-low voltage CPU chip that's
actually considerably faster than its "number" indicates. This
also improves battery life. With the introduction of the Intel
Centrino and Dothan, the Intel-based Tablet PCs will be
comparable with faster desktops. As an example, according to
Intel, a Centrino 1.6Ghz processor is comparable to 2.4Ghx
Pentium4-M.
Some Tablet PC models are including a CDRW-DVD drive within the
unit. Some have USB or firewire models available. There are also
third party drives available.
The Tablet PC can use the pen technology in PowerPoint
presentations, etc. These annotations can be saved for future
presentations or erased completely. Using a Tablet PC with a
projector allows the presenter to annotate slides, etc as he
speaks.
The Tablet PC can be used in both portrait and landscape modes.
A touch of the button changes it instantly. There's no need to
reboot.
Tablet PCs generally use a 1024x768 screen resolution.
High-resolution displays and Microsoft's Clear Type display
technology make the Tablet PC an excellent reading platform.
Video is also improving with one model offering a resolution of
1400x1050.
Some Tablet PCs offer fingerprint scanners for increased
security. There are also 3rd party devices such as USB pen
drives that contain a security lock. Without the pen drive, the
information on the Tablet PC is irretrievable.
Tablet PCs are changing the way we use computers. They'll
continue to do so and in more ways than we're currently
envisioning. As this year progresses, expect to see more
innovations in features and size and even more availability and
features galore, including dual core processors and better
graphics.
