I had an Atari Lynx it was a battery eater. It reminded me of the Amiga in graphics and sound. I gave mine to a friend who started a computer museum.
Some of the games you never thought possible on the Lynx, Hand Made Software did a good job of that.
Indeed, on both points. I never use batteries on mine any more, just straight into the power adapter. There are very good home brew games coming out too.
