There is nothing that requires a new device "product X" to get the attention from inquisitive senior-tech heads, but the Viliv Tablet PC maker, product x is actually referring to its forthcoming range of tablets, 7 X, X 10 and X 70.

X 7 X 10, powered by Google Android operating system, and come up with a seven-inch and 10 inch screen, it is not difficult to work out which is which! It is believed that the devices come with Wi-Fi, but speculation is that 3 G connection, which is better in many cases.
The X 70 is another matter entirely, it will with Windows Mobile 7, but it is asserted that this Tablet is going to be the lightest and slimmest Windows Mobile 7-powered device around.
Prices are obviously not known as the big release will take place at CES 2011.
