Apple's new iPad: 3+1 = Retina. Apple presents two new iPads. The Mini is small and the 4th version of the iPad is named "iPad with Retina display". Got it? The question is: do the A6X chip, a better front camera and Lightning interface justify a new name?

You can decide that which device you want to buy:
Smartphone, laptop or tablet. But I think Tablet device is best for the businessman because of many reason. Many branded company sell their tablet but you should take a look on some tablet review site before you buy it so that it will help you to have some knowledge about its feature, its benefit, U can compare them for justifying that which of them is best.
http://whattabletisthebest.com/ is a same liked site where many people said their experience, review and comments about using tablets. You also can take a look on there.
I was just wondering why the "games performance" category received a score of only 50%. To me, the iPad excelled in gaming performance, as quoted below:
"Thanks to the high CPU and GPU performance, new games are no challenge for the iPad 4. We ran FIFA 13, Real Racing 2 HD and Epic Citadel on the tablet. The two games run fluidly and the control is easy thanks to the precise touchscreen and sensitive gyro sensor. The iPad 4 is a great gaming console, but the measurements and weight are not ideal."
