Apple’s New iPad


I have noticed that, on my new iPad, parts of the back get warm or even hot from time to time, something I didn’t experience on the iPad 2. Is this just me?


No, I’ve had a number of others tell me the same thing, including some who described their iPads as getting “hot.” While I didn’t notice this on the iPad I tested for my review, I have noticed some mild warming once or twice, briefly, on the new iPad I bought for myself. The company says that, because of the larger battery and the greater power being consumed, it wouldn’t be unusual for parts of the back of the device to feel warm from time to time. If it gets uncomfortably hot, I would advise you to take it back to the store. Apple says it shouldn’t get so hot as to be uncomfortable to use.

Consumer Reports said Tuesday that it had run lab tests showing the new model runs up to 13 degrees hotter than the iPad 2 when playing an action game uninterrupted for 45 minutes. But the magazine said: “When it was at its hottest, it felt very warm but not especially uncomfortable if held for a brief period.”


I have read that, because of the higher resolution on the new iPad, apps and content will take up more space. Does that mean I either have to keep less content on the device, or buy a model with more capacity?


According to Apple, it all depends on the app and the nature of the content. The company says apps that are very graphics or photo intensive may swell in size if they want to take full advantage of the new, sharper screen. Others, which mainly rely on text, can either stay the same size or grow only slightly.

As for content, the biggest issue will likely be photos and videos taken on the iPad itself, which create dramatically larger files. I suspect relatively few people will use a large tablet frequently as a camera. And because of the screen, some people may be tempted to download more high-definition videos, which take up more room. Whether you need a model with greater capacity depends on what kinds of apps and content, and how much, you plan to store on it.


I bought the new iPad and agree with you that text is incredibly sharp, but I’ve run into some apps—including The Wall Street Journal’s—that looked fine on the older model, but fuzzier on the newer one. Are developers upgrading their apps?


Apple says that most text, even on older apps, still looks sharp, because they use the iPad’s built-in fonts, which have been adjusted to match the new screen. And that has been my experience. However, on some apps, text looks more pixilated on the new high-resolution screen, because they use custom fonts. Developers are starting to release updates to fix this issue, as well as to sharpen their graphics. As for the Journal app, the publisher says a version that is retuned for the new display is in the works and is planned for release around April 1.
