BlackBerry-Playbook-LTETablet PC sales are on the rise. Market analytics group Gartner Research predicts that by 2016, over 369 million media tablets will be sold. Though Apple’s iPad currently has a majority market share, Gartner predicts that proportion will steadily decrease.

More people are finding that their affordability, versatility and portability make tablets an attractive commodity.

For those in the business and technology sectors, tablets are more than commodities. Many enterprises find that a tablet PC for business like the BlackBerry PlayBook is ideal for their employees to use.

Tablets are ideal for business networking and corporate management because while they are not cumbersome, they have a wide range of applications. In some cases, they exhibit very high computing power and come with the security features necessary for certain lines of work.

Tablets, in short, are hot.

But in today’s market, one does not merely buy just any tablet. The current marketplace contains an impressively wide array of manufacturers, styles and prices.

This begs the question: If tablets are hot, which tablets are hottest?

Four tablets have appeared to separate themselves from the rest of the field: the BlackBerry Playbook LTE, the Google Nexus 7, the Amazon Kindle Fire HD 8.9” and the Samsung Galaxy Tab.

Android tablet PC sales indicate that Android tablets are gaining on the iPad, according to Tech Thought’s Sameer Singh. By the halfway point of next year, Android’s popularity is expected to be greater than the iPad’s.

That’s why three of the four tablets are Android tablets and the fourth, Research in Motion’s BlackBerry PlayBook LTE, recently debuted a new feature that allows users to run Android apps on their PlayBook, according to Crackberry.com’s D.J. Reyes.

The BlackBerry PlayBook LTE is also one of the most enterprise-ready tablets on the market. Long held as one of the industry exemplars in mobile security, RIM has developed programs like BlackBerry Enterprise to help effectively manage the technology and communications sectors of businesses.

When BlackBerry 10 is released this January, the already-strong enterprise reputation of BlackBerry will receive further fortification.

BlackBerry Balance, a program which allows users to separate files and apps between the personal and professional areas of their tablet or smartphone, is one of the most-anticipated features of BlackBerry 10.

BlackBerry broke into the technology world with their revolutionary smartphones. Amazon broke into the technology market with their Kindle e-readers, but has managed to produce a competitive tablet as well.

The Amazon Kindle Fire HD 8.9” is one of the best-reviewed tablets on the market. Though it’s priced at $499, its 1900 by 1200 pixel resolution and Imagination PowerVR 3D graphics make the price tag worth it for many.

Google’s tablet, the Nexus 7, has also seen critical and commercial success.

The Nexus 7 costs just $199.99 but last up to 10 hours on a single charge. Its display screen is only seven inches, leading many to think of it as a precursor to the iPad Mini.

Another Android competitor is Samsung, whose Galaxy line of smartphones and tablets has proliferated tremendously in the past two years. Samsung offers many customizable features, so buying a Galaxy tablet or smartphone means that customers can customize their device to get just what they want in a tablet.

Customers, after all, want choice. And in today’s surging tablet PC market, that’s just what they receive.
