Which smartphone should I buy?

[MasterFlea]

My old, old phone needs to be replaced. I am now venturing into the realm of smartphones but I haven't a clue.

I've only a small budget, around £100 so it can't be an iphone.

So what would you buy on this budget?

I had a look at the Nokia Lumia recently and didn't think it was very user friendly.

I have a HTC One, it's really good, I like the screen size. Go to your local phone shop and try them all out.

And don't forget to get a proper cover for it.
