For me indispensable

The Apple Smart Cover is essential in our two iPad Air. In combination with a TPU casing for the back which has a section for the Smart Cover, all parties are adequately protected. If you hold the iPad while lying down, can easily remove the cover to reduce the weight as it is only held by magnets. When it turns off on the table, one can thus relatively stable upright angled up the iPad upright or flat. The only thing I want to complain about is that this is possible only in landscape mode. Maybe Apple make it so, a similar folding technology, as with the Origami Case by Amazon for the Fire HDX implemented, integrating, then my last wish would be implemented for feature Tablet Covers.
So there is still room for improvement for ingenious engineering, the product gets in spite of all advantages and no 5 stars from me.
