Can you help me choose a chromebook for school please?

I'm replacing my school iPad with a Chromebook because I find typing on the iPad a pain. All I really need do to is use google drive and be able to browse long edu articles. Battery life is also a big plus for me. With the new HP Chromebook announced, I started looking for a new laptop again, but had no idea which Chromebook to buy. Any advice?

- I say a Chromebook due to it's small weight and cost as I have a far better desktop at home.
