I'm not Apple Fan Boy, but I do like iPods, specifically the shuffe. Best sports/running audio player Iv ever owned. It wont fall off, the charge lasts for a good 8 hours of playback at high volume. However I lost my charger and tried to buy one off of Amazon, first a $3 one, then a $8 one, none of them worked. I ended up coughing up the money to apple and hey it worked.
My brother gave me his old iPhone 3gs and I use it for video games on the couch. Same problem, again tried cheap 3rd party cords they all failed. Got a real one and it worked.
I do think this is going a bit far, but since iv been burned in the past I can kinda see where they are coming from. It weeds out the bottom feeder rip off artists.
