Query: Broke Twice in Two Years

When it worked, it was great.When it worked.First, like in other reviews, one day it just died. Luckily, it was under warranty and Samsung did fix it. They said the motherboard got fried, but all I did was charge it...?Then, over the past few months, the screen started to get dimmer and dimmer, so that I can't watch any dark scenes at all in a normally-lit room. Trying to watch Sin City was like listening to a radio show with occasional white flashes on the screen.Finally, tonight, the thing just died again. Since it isn't covered by the warranty anymore, this time it goes in the trash.
