the bend won't really affect ur applecare.
for example, if ur battery died prematurely or ur logic board/optical drive fails, it will still be covered under applecare.
only accident that voids ur warranty and applecare is liquid damage.
Not true. If you read your terms and conditions, any damage that is caused by a drop or impact is also not covered. That's not the full limitation either, but it's the relevant one. In addition, I have posted personal experience as an Apple Tech of having repairs rejected for less significant damage than this. Please don't spread misinformation.
Exceptions to the repair policy for damage like this are few and far between, btw. If you've gotten one, good for you, but the chances of that happening are exceptionally slim. Apple knows that they have no responsibility for damages like this.
