Impossible to even attempt to answer with your OP. It's a subjective matter. You need to tell use what your needs/wants/priorities/preferences/budget/etc are if you want feedback.I currently have an iPhone 5 and Macbook Pro Retina 13-inch... Do you guys think I should get an iPad as well? If so, which one?
Try browsing the countless other "Should I get an iPad?" and "Is an iPad worth it if I have X/Y/Z...?" threads.
