Keyboard appearing on mobile devices

[GoogleCodeExporter]

Discovered this whilst browsing the Go Tour on my iPad, when new pages of the 
tour are display (pressing previous/next) the software keyboard is displayed 
every time. I am unsure whether this is the intended behavior of the Go Tour, 
but regardless, it was very frustrating on a mobile device.

This is being caused by line 185 of /static/tour.js 
(https://code.google.com/p/go-tour/source/browse/static/tour.js#185):

181        } else {
182                $('#workspace').show();
183                $output.empty();
184                editor.setValue(load(i) || $s.find('pre.source').text());
185                editor.focus();
186        }

I propose that setting focus of the code area should only happen when the 
client is known to have a hardware keyboard. This may be a rather big ask, so 
instead, don't set focus on a mobile device.

Any idea how to reliably detect when we're on a mobile device?

A quick and simple way as discused here http://stackoverflow.com/a/3540295 is 
to check for keywords in the user agent.

if( /Android|webOS|iPhone|iPad|iPod|BlackBerry|Windows 
Phone/i.test(navigator.userAgent) == false) {
        editor.focus();
}

N.B. I have included Windows Phone in there too, seperate from the SO answer.

Projects like http://detectmobilebrowsers.com/ offer more robust solutions for 
multiple platforms, they appear to have jQuery script, so that should fit right 
in with the Go Tour already.

Removing the call to editor.focus() completely (for all platforms) is another 
option.

It's simple, keeps the experience consistent across browsers and isn't a huge 
loss.

Choosing to edit the code requires enough activity that an extra mouse click 
won't be a burden.
