My family is going to buy me a smart phone which costs less than 1k. My needs are:

Big screen as I will be reading lots of stuff (PDF ebooks etc) on it, and watch youtube videos on it as well.

Good sound quality because I will use it a lot to listen to music. I am planning to listen to it while jogging.

Decent memory because I have some music files and PDF documents to store.

Processor need not to be too good because I will not play games on it and since reading and listening to music doesn't require too much processing power anyway. It is good enough as long as it doesn't lag.

Can check email/facebook/google maps/GPS/youtube

Camera also need not to be too good. Not much use as of now.

Can use WiFi.

Durable. Planning to use at least 4 years?

After some research, I plan to buy a ZTE Acqua V880E. Any thoughts?
