Apple hasn’t tinkered much with the design of the iPad since the first model. The current version is slightly thicker and heavier than the second-generation one. This makes room for the larger battery needed to power some of the new features. The differences are minor, and most people would have a hard time noticing them without a careful examination.
Overall, the device is 9.5 x 7.3 x 0.4-inches and 1.4 lbs. That makes it smaller and lighter than virtually every laptop, about the size of a magazine, and roughly the weight of a hardback book. There are some who are hoping Apple will introduce a tablet that’s smaller than the current one, but I find this one has hit the “sweet spot”: large enough to handle everything it is asked to do, small enough to be very portable.
Much of the attention given to the third-generation iPad has centered on its 9.7-inch display that has a resolution of 2048 x 1536 pixels. For those who are counting, that’s four times as many pixels as are in Apple’s previous versions, with 264 pixels per inch. That makes each one so small that, in most situations, individual pixels can’t be discerned with the human eye.
Trying to describe how great this screen looks is a challenge. The best I can come up with is to say that you could hang this device on the wall, put an image of the outdoors on it, and people could easily mistake it for a window.
