I'm having an issue with a Surface. User agent is Mozilla/5.0 (Windows NT 6.3; ARM; Trident/7.0; Touch; rv:11.0 and it's not detexcted as a touch-capable device:

{'device': Device(family='Other'),
'browser': Browser(family=u'IE', version=(11,), version_string='11'),
'os': OperatingSystem(family='Windows', version=(), version_string=''),
'ua_string': 'Mozilla/5.0 (Windows NT 6.3; ARM; Trident/7.0; Touch; rv:11.0) like Gecko'}
