The left side of the slate houses a headphone jack, micro-HDMI connection, micro-USB 2.0 and a full-size SD card slot that lets you add up to 128GB of external storage (and theoretically more).
There's a full-size SD card reader and a standard 3.5mm headphone jack (with mic support) on the left, plus the power input, HDMI output, USB 2.0 port, USB 3.0 connector and SIM slot (currently unused) in back.
The optional dock offers the same features it always has, but for any first-time Transformer buyers who might be reading this, here's a quick primer: in addition to being an external keyboard, the dock is home to an SD card slot, a full-size USB 2.0 port and a built-in 19.5Wh battery, allowing you to go longer without charging your tablet.
