MP: In today's market, Id expect to find a relatively low-res screen like the iPad minis on a tablet that's priced a lot lower - not on a major product from Apple. The market has evolved, and high pixel density -- which Apple itself pioneered with the third-generation iPad -- is now the norm. After using a display with higher pixel density on my phone for more than two years, I'm not willing to go backward and see all of those pixels on a tablet. The reason is simple: I spend a lot of time looking at my tablets display.
So there's no getting around the fact that the iPad minis 163-pixels-per-inch resolution is not only paltry, its not even close to being competitive. The Nexus 7s screen is 216 ppi; that's not even the highest in this size class, but it is far superior to the iPad minis display.
Dimensions and weight
CB: The Nexus 7 is easier to hold than the iPad mini if you like to wrap your hand around your device. That's because, again, its narrower than the iPad mini. If, however, you tend to hold the tablet by its edge, the iPad mini is (I find) a more comfortable device to hold, because its lighter. If I switch between the two, the Nexus 7 feels heavier -- and, at 0.75 pound compared to the minis 0.68 pound, it is heavier.
MP: No question that the Nexus 7 is heavier; lighter tablets such as the iPad mini (and Barnes & Nobles Nook HD) are friendlier to hold one-handed for long reading sessions. That said, I think the Nexus 7s weight is still acceptable for such sessions.
CB: If you're looking for the greatest possible capacity, the iPad mini has it at 64GB of storage; the Nexus 7 tops out at 32GB.
MP: The bigger question is whether you'll want to spend $529 on an iPad mini to get that much storage.
Its true that the Nexus 7 tops out at 32GB. And unlike most other Android tablets, the Nexus 7 has no MicroSD expansion slot, so you cant add storage. But I will say that -- like all Android tablets the Nexus makes managing that storage space easy: Because your computer sees it as a mass storage device, you can just drag and drop content over to the tablet. (If you're using a Mac, you'll need to download the Android File Transfer application to access the Nexus's storage, which doesn't appear on the Macs desktop.) The iPad mini still relies primarily on iTunes to transfer content locally, as opposed to accessing it through the cloud, so I find the Nexus 7 easier to use.
CB: The front-facing cameras on the two tablets are both 1.2 megapixels. The rear-facing camera on the Nexus 7 is&well, missing.
