Query: liter then air

I have been playing my son's DS for a while now; he has Animal Crossing and we have fun with it. I just got the Lite today and have been playing Brain Age - clever program.The feel of the lite is much nicer; the screen easier to read by my old eyes. Its a well designed system; I found the touch screen and HR recognition great (much better then my daughter's Leapster.I don't think the microphone sound recognition is that great. I'm in a somewhat quiet room - a little white noise from my AC and computer. It didn't understand the word BLUE very well.The system is a great toy and fun fiddle.
