What they fail to realize is that this fight is not a fight for myself, it is a fight for others. Yes...... it is not a fight for me as I do not have plans to ever school in Nigeria neither will my children. Your children may school in Nigeria and they might be unfortunate to be a victim of circumstance by a lecturer someday.
AppleCare (not AppleCare+) doesn't cover accidental damage, such as cracked screens on iPhone, iPad, etc, and usually for devices that are not covered by AppleCare+, regardless if they are covered by AppleCare, they are subject to non-AppleCare+ fees to replace the screen.
In reference to your Ballpark Idea : I have just gotten off the phone with Dell in regards to replacing my screen. It is cracked in the corner but still in working condition. Dell Venue 8 Pro. For them to replace the screen I was quoted $269.00. Per Dell, and the tablet is still under warranty, but their warranty does not cover accidental damage, so I am assuming that not much is really covered. Upgraded warranty I have no idea.
