Doesn't make the Nintendo DS an inherently bad item, it most likely just means your guests were rude. :tongue_smilie:
I'm always a little perplexed when people say things such as, "Oh, my kids read books on road trips and we play games." That's great, but playing a video game in the car and reading aren't mutually exclusive, you know? When we take road trips that involve spending 2-4 days in the car at a time while covering a couple thousand miles my kids look at books, they draw, we listen to music, they nap, they gaze out the windows, they play with small toys, and yes- they also sometimes play games on either the DS or the iPod. It's just one more tool in the kit to keep them entertained for such a long time.
