Choose me! Choose me! 
Really, I've had my Sony PRS-500 for almost two years now, and it's almost always with me. But, it's been acting a little weird since the accident the poor thing had (I told it not to go near the bathtub unattended), and I fear it will leave me soon. I do dread that day, as I don't know how long it will take me to get a replacement (I know it wouldn't want me to be alone).
This contest could solve that problem, quite nicely.
