This is a most excellent place for technology news and articles.
They fit in a pocket.
They look super thick though. I can't imagine that being very comfortable in a pocket.
No thicker than a wallet.
Not really noticeable unless you wear super tight clothing and you get used to the weight.
I would kill for a smaller sized phone at an affordable price and good/decent spec.
