While user agent can be spoofed (and pretty easily with most browsers), the reality is it's not a problem you need to worry about. You do generally want to try and avoid user agent when possible, but if your trying to detect the device purely on the server, there really isn't another option. Any kind of client side detection (such as screen width) will require and least a two trips to the server--once to serve up the client-side code that detects the device, then you hit the server again to change the layout.
