Amazon Kindle. I've got to admit I don't read much so haven't found much use for it. But this thing is incredible, the screen is just the most bizarre thing ever - it does look exactly like paper; unbelievably thin.
The battery life is amazing - I have had it for around 3 months and have only charged it once; currently on around 60% battery. OK, I haven't used it much but then I don't use my phone excessively either, which barely lasts a day.
