History of the browser user-agent string

a plea to developers out there: please respect the user-agent string contents even when you know it's a mobile device by other means.

if a user has gone to the trouble to manually set user agent, it's no accident -- it's an attempt to avoid the buggy crap that so many sites "customize" for mobile.

e.g. Stubhub, TV Guide, TicketExchange, ...

And, no, I won't let you track my location, so stop asking.
