i have had a 5th generation 30gb ipod for 18 months and after dropping it, from a small height onto carpet, it has broken. my only choice now is to get a replacement. so is the ipod touch a good model to spend my money on? Are they reliable, recomended? my main interest is playing music, the other features are of less interest to me, i just ned something that is going to last. any thoughts here please?
