The full potential of using a tablet on-the-go is truly unleashed when cellular service is attached to it, and the HP Slate 7 HD and Slate 10 HD give you a taste of that freedom with two years of free T-Mobile data service. The similarly specced 7-inch and 10-inch tablets come with 200MB of data per month for twenty-four months.

The Slate 7 HD and Slate 10 HD are the same tablet, just in 7-inch and 10-inch models, and both have 1,280x800-pixel resolution IPS screens and Marvell SoCs with 1GB of RAM.

The Android 4.2.2. tablets come with either 16GB or 32GB of internal storage and house microSD expansion slots. Like other HP devices, the Slate 7 HD and Slate 10 HD have built-in Beats Audio features that enhance audio performance when using headphones.

The tablets' backs boast a comfortable grippy weave-like texture and the 7-inch version comes in silver, while the 10-incher has both a silver and red option available. The back is also home to a 5-megapixel camera, with a 2-megapixel shooter on the front.

Both the 7-inch and 10-inch tablets felt relatively thin and light for their respective form factor. The grippy textured back combined with the rounded corners and curved edges made them comfortable to hold in either one or two hands. Touch screen responsiveness was fast and performance was smooth when navigating between apps.

According to HP, the Slate 7 HD and 10 HD will go on sale in November. Pricing has yet to be announced so check back with CNET for updates and a full review once the tablets become available.
