I could but I would still have to send the client to some url to get his browser data so I know what to look up. If I'm sending a client a url, why not take it 1 step further and eliminate any work on my end by just providing me the correct screenshot and info? Then I can shoot a client an e-mail, ask him to click a link and seconds later I'm looking at what he's looking at with his browser settings without having to do anything.
