Update: Regarding readability under the sun (which is a fair question), the PadFone Station was almost just as good as that on the Transformer Prime — both have
an optional outdoor mode that boosts the screen brightness for this purpose, which is why they perform much better than the original Transformer.
To be fair, some of its
optional features are handy: Holding the recent apps button can take a screenshot; an «
Outdoor» volume toggle loudens the speakers; another
mode makes the screen easier to use with gloves; a simplified «Kids»
mode could help parents; and a quick setting to kill off wasteful background processes is nice.
