Apple Now Making 56 Different iPads
Apple has made it easier than ever to afford a new iPad, but it has also made it harder than ever to choose one.
There are now 16 prices to pick from: $249, $299, $349, $379, $399, $429, $449, $479, $499, $529, $579, $599, $629, $699, $729, $829 and those prices cover 56 models of the iPad across 5 models, 4 memory configurations, 3 colours and 2 screen sizes.
This doesn't even cover the need to choose whether you want the TouchID fingerprint sensor or built-in 4G wireless
The newest iPads bring with them some changes from last year's models, but on the Mini 3 that TouchID is actually the only major functional addition from a year ago.
This can get very confusing for new Apple buyers especially those trying to choose online and in Apple shops.
