I would say Nintendo is the one I respect the most.
They have been a game company right from the start back in 1889
They consistently innovate with hardware - analogue stick, rumble, motion control, virtual boy :P
Their software and hardware are typically high quality.
On a side note I lost my respect for Microsoft due to the blatant design and manufacturing defects on the 360 were outrageous.... real pity because the original XBOX was a fantastic system.
