Tablets are book-sized PCs that operate without keyboards (some offer keyboards and while some Tablets offer pointing devices known as Pens/Stylus). Tablets operate like smartphones but with larger screens and work the same way as a laptop with the only difference being they have a small ROM compared to laptops.
iPads are considered the best tablets in the world. Like iPhones, iPads are the best selling tablets in the world. iPads are high-end products that speak of one's status. Owning an iPad is considered advantageous than owning any other Tablet brand no matter their cost.
