In British English you might use 'of' for a specific thing, eg. a book or person, and 'on' for a broad topic, eg. 'your opinion on string theory'.

But it's not a very strong rule, I wouldn't feel that either was wrong. This may be the effect of American English usage of 'on'.

Thanks @mgb. I understand... I should say We surveyed drivers' opinion of this device? –  Stat-R Mar 29 '12 at 15:32
For example: I do not give my private opinion of my nearest relations. –  user19148 Mar 29 '12 at 15:32
@Stat-R: You've got mgb's distinction right, in that this device is a specific thing, so opinions would normally be of it. But it should always be drivers' opinions in the plural for your construction. –  FumbleFingers Mar 29 '12 at 16:28
Thanks you @FumbleFingers –  Stat-R Mar 29 '12 at 16:30
I don't there there's any difference between British and American usage here. –  Peter Shor Mar 29 '12 at 18:24
