Despite its name, the 7.9-inch iPad Mini is one of the largest among the mini-tablets.

It doesn't feature a camera and focuses on Office software, which suggests Microsoft is focusing this product on an executive toy. There's no 3G connection (only Wi-Fi) so owners won't have to worry about an extra contract. The real delight, however, is Metro, the impressive navigation interface .It is beautifully designed with brightly colored squares for navigation.
