The HP Slate7 Voicetab, as its name suggests, is one of those compact tablets that you can actually use as phones. Awkward as it is, you can lift it up to your face and have a call on it as you would with a normal phone(well, kinda).
HP will be offering the Slate7 Voicetab with an optional Datapass mobile data service. That includes 250MB of data per month for 2 years.
The 7-inch screen of the Slate7 has a resolution of 800 x 1280 pixels. It has really nice viewing angles.
