Though Asus’ keyboard docks are optional add-ons for the company’s line of “Transformer” Android tablets, the existence of “Transformer” in the naming scheme denotes the ability to use the tablets like tablets or dock them into keyboard/touchpad combos for more laptop-like use.
The docks also house their own batteries for lending additional power to the tablets. Asus promises between 14 and 18 hours of juice, depending on the model. Prices generally range between $100 and $160 or so (here’s Best Buy’s selection, for instance) at retail.
