I have an ASUS chromebook which I use for most things. I love it.
You do have to get used to using onedrive or google docs (I prefer onedrive) if you want to word process, but I'm fine with that.
I paid a bit more to get one with bigger RAM (I think? I'm not very techy, and went on a friend's advice, it might have been something else that I got more of :-S ), but it was still just about £200.
I have had a range of laptops in the past, and none have lasted more than a couple of years. The chromebook is not showing signs of wear or slowing, so I am pleased with it. I have not been impressed with Acer machines which I have had previously, but always find Asus better.
