[citation][nom]waffle911[/nom]The GameGear and Nomad were both far superior to the GameBoy of the same time period, technically. They had Backlit color displays and 16-bit graphics, while the GameBoy sported 2-bit greyscale and no backlight.But 6 AA's for 6 hours (2 hours for the Nomad!) was ridiculous, especially when rechargeable batteries were still expensive and impractical. Not to mention the cost for the system itself (when new). But still, the Nomad was pretty cool for being a (nearly) complete mobile Genesis with TV out and two-player capability.[/citation]
The Game Gear was basically a portable Master System, but with lower resolution and a much higher colour pallet. The Nomad was a portable Mega Drive/Genesis. Even the Game Gear had much more horsepower than the Game Boy. Don't think it was more powerfull than the Game Boy Color, though.
