Sizing Up the New iPad Mini
By WALTER S. MOSSBERG
.
So why did Apple, whose large iPad and new Macs boast extremely high screen resolution, choose a lower resolution for the Mini? The company did so because it says there are only two resolutions that allow its tablet apps to run unmodified. One is the extremely high resolution on the current large iPad, which would have boosted the cost and lowered the battery life of the Mini. The other, the one Apple chose for the Mini, is the same resolution on iPad models consumers have snapped up: the original iPad and the iPad 2, which is still on the market at $399.
This makes sense, but it means that, unlike its closest competitors, the Mini can't play video in high definition. Apple insists the device does better than standard definition, if you are obtaining the video from its iTunes service, since iTunes scales the video for the device, so it will render somewhere between standard definition and HD. It says some other services will do the same. But the lack of true HD gives the Nexus and Fire HD an advantage for video fans. In my tests, video looked just fine, but not as good as on the regular iPad.
