As for its hard key layout, all of those buttons (volume, power and dedicated camera key) reside on the right, with nothing but a 3.5mm headphone jack up top and microUSB port at its base.
The volume rocker and dedicated camera button are positioned along the unit's right side, with the power button and 3.5mm jack up top and a lone port for microUSB at the base.
Starting with the base, the back side features inputs for power, a 3.5mm line-in jack (sadly, you can't bleed in your PMP with the TOSlink feed), an optical input and a sync button.
