There are only two potential downsides: price and size. The cheapest 16GB Wi-Fi-only model will set you back £399, while the most expensive 64GB Wi-Fi and 3G edition costs a hefty £659.As for size, it's heavier and less portable than the new iPad mini, so it's not as easy to throw in a bag or hold in one hand during those long commutes. This may or may not be a problem for you depending on how you use your iPad, but it's something to bear in mind when weighing up which model to buy.
