Following the iffy exit of HP from the tablet arena, we’ve got two new companies ready to play the game.  First off, we have Sony announcing the pre-sale of Sony Tablet S before it hits the racks in September.  The new device boasts a powerful NVIDIA Tegra 2 CPU processor and a 9.4-inch touchscreen display, making it well-suited for rich media consumption.  It also features Wi-fi compatibility, front and rear cameras that can capture still images and record videos, and support for USB (micro A/B) interface and SD card for transferring files and data.  The Sony Tablet S runs on Android’s recent operating system—version 3.1.

“The Sony Tablet S delivers digital content, rapid performance, and remote access functionality in a unique and convenient product,” said Doug Wilson, President & COO of Sony Canada. “This device demonstrates a seamless Sony entertainment experience offering consumers smooth access to videos, games, books, and more by combining Sony’s premium network services.

The new tablet will be available in 16Gb and 32Gb for $500 and $600 respectively.  You can buy them off Sony direct and online stores, as well as other authorized dealers.

HTC also releases its first ever Google Android tablet, with support for AT&T’s upcoming LTE network.  The HTC Jetstream tablet boasts a 10.1-inch display that works with a digital pen accessory for note-taking and drawing. It also sports a 1.5 GHz dual-core Snapdragon processor, support for today’s HSPA+ mobile broadband networks as well as future LTE networks, a new version of HTC Sense software for improved usability and dual camera sensors, including an 8-megapixel rear camera.

“HTC Jetstream combines the acclaimed HTC Sense experience with Android Honeycomb to provide an innovative and engaging experience on a 10.1 inch tablet,” said Martin Fichter, acting president, HTC Americas Region. “Paired with AT&T’s upcoming 4G LTE speed and mobility, HTC Jetstream delivers connectivity for social and entertainment needs alongside productivity and creativity tools in a portable package.”

The drawback about the new tablet is that it didn’t learn much from the mistakes of Verizon and Motorola Xoom.  An overpriced tablet supplemented with a ridiculous plan will never sell well.  See, AT&T offers to supplement the Jetstream with a 3-GB data plan for $35 a month so the customer can buy the device for only $699 instead of $849. Seriously, what makes it better than the iPad? The latter is cheaper and doesn’t need a contract.
