You can use the iPod Touch to listen to music, watch videos, watch photos, listen to audiobooks, read ebooks, play games, manage your agenda and to do-list, check your email, surf the web, check the weather forecast for wherever your are that moment, buy music, keep track of your investments, take notes, chat, tweet, check radar and satellite images if any rain is coming your way, … Not even mentioning the extras on the iPhone. That you can use it to analyze your sleep pattern surprised even me.
