There seems to be a brand new tablet pc announced every month, as
manufacturers run to take advantage of publicity showered on the Apple
iPad 2. Since we couldn't keep track of every tablet laptop launched,
we've gathered a list and overview of the tablet market.
Apple iPad: By selling million plus iPad's within
first few weeks of the launch, Apple iPad has proved its supremacy in
the world of tablet pc. Of course, the initial tablet version had
drawbacks; however we can't really deny the fact that millions were
bought at the staggering rate.
iPad is easy to use and, has a wide range of exciting games with web
apps which are considered as some of the powerful aspects. iPad 2 comes
with two cameras, one in the front & other at the back, quality
media playing and notable ebook reading ability. Apple is also using a
common operating system called iOS in all the popular products; iPad,
iPhone, and iPod Touch.

Android tablet: Available in different sizes from
over dozens of manufacturers, these tablets run on Google's operating
system, known as Android. Android tablets offer a lot of options, if you
don't really like Apple's iPad for any given reason. Popular example is
of Samsung Galaxy Tablet.
Windows tablets: These tablet pcs have continued to
develop and perk up since 90s, and have been running on Microsoft
Windows operating system. If you are looking for something between a
laptop and a smartphone, however with a laptops experience, these
windows based pc-tablets are the best you can get in the market today.
You can also use physical keyboards hidden behind the touch screen of
these elegant convertible tablet pcs.
Various other tablet pcs: Most of the tablet
manufacturers are using Microsoft Windows or Google Android as the
operating system on their products; however some companies are trying to
imitate Apple iPad by starting from zero to build a new tablet pc that
may turn out to be important brands in the near future.
Apparently, if you're a huge fan of Palm WebOS (bought by HP) or the
BlackBerry, you would know that the two highest-flying examples of these
are HP's WebOS-based tablet pc and BlackBerry PlayBook from RIM.  Even
then, these tablet computers will take quite some time to gear up to the
level of competition from Apple iPad and various other notable tablets
being offered in the market.
E-book readers: They were once simple tablet
computers with screen sizes ranging between 5-10 inches, and can be used
to read e-books, e-newspapers and e-magazines. Common examples are
Amazon Kindle from Amazon; Barnes & Noble came out with Nook Color,
and Sony's very own Sony Reader.
In addition to new technological advances and features, they embrace
all or most of the qualities of conventional e-book readers (e-ink
screen, black & white contrast, ebook stores etc) for long reading
sessions and are quite in-expensive.
