To add to the great advice firedept10 already gave you; the ipod touch can only send texts over iMessage via WiFi, so those who she sends texts to must also have iMessage (which is only on Apple devices). If she want's just pure texting to and from anyone regardless of device (without iMessage), then the Android smartphone she has will do fine. An Apple smartphone, however, is the best of both worlds. Great for music and for texting.
