1) No USB port(s)
2) No HDMI port
3) No power built-in (have to use the adapter that came with tablet. Aargh!!)
4) No SD card slot
5) No micro-SD card slot
Expensive piece of plastic for the price.
But, it does offer a remote control, and a headphone jack!!!
(ASUS messed up by not including a full-USB on the TRANSFORMER, but made it up in a big way with the features on their dock.)
Acer, are you listening? You can surely come out with a much better dock.
Save your money and don't buy this dock.
