+1 for Garageband. It works well, sounds decent and is extremely portable.
I would like to pdf some of my lyric sheets or tabs... but that is effort.
Other than that, we find that it is a very expensive TV.
Great for watching ABC shows while washing the dishes. Overall, it is a cool device. Always on, so a quick grab, and you are surfing the web or replying to an email. It is app driven so I find that I am not editing Word documents or Excel spreadsheets. Excellent for travel.
