I would certainly say PC, Mac, or Apple IIe, or maybe even C64. I could make an argument for each one. But, since you narrowed it to just consoles that makes it far harder.
I guess I would have to go with NES as that was my first introductions to JRPGs, Dragon Warrior. Unfortunately almost every JRPG to date has been a clone of DW1 (with small iterations), so that first JRPG game I played was the one I enjoyed the most. But I keep trying and hoping to regain that magic feeling from the early 90s
My prediction (Jan 15th, 2008), total sales by end of 2008:
Wii - 35 million
X360 - 25 million
PS3 - 21 million
