First, numonex, you appear to be from the UK. Is this is any way related to our current Uni places problems? Are you one who's been denied because of lack of clearing and full Universities?
Eitherway, my degree only helped me gain my job, having a load of experience in many computing related topics helped me have options but the career I wanted and am now in (web development) was not taught at all in a 'Computing' degree. Weird that considering that is what the industry was.
Of course what they didn't tell me is that because every career advisor was saying do computer related stuff to every pupil in the country, when I came out of it there were no good jobs and what you learnt was out of date anyway.
That aside I think it depends on what you want/need to do. A good uni course can be a great stepping stone into many industries but there are some that don't need it, some more physical jobs or one that can be learned while working (apprenticeships) can benefit more.
