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.
Now the one down point about this is nothing related to the device itself, only the whole point of the thing - the books available. Harry potter for instance is not available from the Kindle store, which is a great shame.
It also includes a web browser, which isn't great, but good enough to update Facebook, Twitter; whatever. The biggest drawback to the browser is the keyboard. It's easier typing with my phone in my pocket, not least because of the bad keyboard, but also because of the slight screen lag, which isn't noticeable when reading but it's a definite issue when typing.
