Finally, HP gets on track with its tablets. The company has focused on Windows slates and its own WebOS products, before canceling the latter. Now, the company has an inexpensive Android slate. As its name implies, the Slate 7 will have a 7-inch screen and it will use the latest Android software and have Beats audio built-in. It’ll weigh in at 13-ounces and should be available for $170 in April.
