Having had my fingers burned twice by portable devices, I would suggest cooling your passions for the nano…
There are many reports about how easy it is to break one of these things. It’s damn easy! I know it wouldn’t survive my usage, and I am a careful user. The nano screen is very fragile, and the IPod regular skips after 20 minutes vibration. Which of itself, can’t be good the the hard drive at all.
Look at the quality of the construction, and consdier carefully the kind of torture you may put that device through.
As with all things Apple, repairs are a huge hassle in Taiwan, are they not? I can’t just take it to the pc shop across the road or wherever.
