Don't come in here and throw rubbish and expect people to brain like this. Manufacturer doesn't COVER your physical damage doesn't mean your warranty is VOID once you scratch your lens, for example.
For a simple fact that, I always had my phone casing scratch last time within 6 months of use and I go to Nokia Service Center to change the casing, stating I will need to pay for such, and my WARRANTY is still VALID for another 6 months.
Like I said, this is a mere whether the warranty is still valid or not by the time the money exchanged. I cannot stand when people come in and throw rubbish fact around.

Even I did support buyers side, I believe it's better to judge this on a fair ground basis. And also,
Demo unit and Used unit are actually the same. You won't know how one use a stuffs, exactly like what you guys deduced on demo unit.
Scratch lens,scratch phone? This is impact damage, with physical internal damage. To be fair,how about making an example with similar scenario, 'I always had my phone dropped and one day I realised that the some functions were not working anymore, do you think if I go to Service centre,my warranty will still be valid even though I don't want to repair?'
And I disagree with you when you said 'demo unit and used unit are actually the same.' Even by the terms definition provided previously in this thread,both are different. Based on my experiences, demo unit resale value is much lower compared to the used unit.
