pple dominated the full-size tablet market with its popular iPad. Now that it released a miniature version of its tablet, will it be able to expand its market dominance?

Apple unveiled the long-rumored iPad mini, a smaller, lighter model with a 7.9-inch screen, instead of the 9.7-inch Retina display on the regular iPad. The screen resolution is 1024 by 768 pixels, the same as the iPad 2 and a quarter of the resolution of the flagship iPad.

The iPad Mini will battle against Google Nexus 7 and Amazon's Kindle Fire HD, which were released early this year. Nexus 7 and Kindle Fire HD already target slightly different audiences from the beginning. The former lures gamers, multimedia enthusiasts, and Android fans looking for the "pure" Jelly Bean experience. The Fire HD is a steal for Amazon Prime members looking to maximize their Amazon membership while keeping tablet costs low, memory high, and the screen mighty.

iPad Mini may stand a chance against the other tablets by offering a powerful device, especially being equipped with 4G/LTE capability.
