I just have this nasty habit that I can't break where I always close my DS when I swap flashcards or micro cards or games I own. I also close It when I have to use the bathroom, eat, get a drink, take the dog out, cleanup stuff, go somewhere in the car, basically do anything else. I usually play in spurts maybe 10 minutes at a time then come back to It 20 minutes later or an hour or more most of the time. That's not really the point though (my habits), If we are gonna be buying something that costs 250 dollars plus tax or more for then we should get hinges that are built on quality and designed well that do the job right.
