Interesting thread for those "in the know"
I started at Tuks in Chem. Eng (didn't know about Comp. Eng at the time) and it was pretty tough. Anyway I moved over to Comp. Eng in first year. Today I work in the SP space and have my M.Eng (Comp. eng) degree. I work with Cisco Service Provider kit and don't even have my CCNA (well I did the whole CCNA and CCNP at Tuks thing) - I just never wrote the tests. At the end of the day, experience counts for more than passing a test. I know of people who just rote learn the Q and A and ace the lower Cisco exams. Obviously a different story with CCIE, CCDE etc.
My plan is to (when I get the motivation), complete CCNA, CCDA, CCIP, CCDP then move onto CCDE... for when I leave the company

Until then it won't make much difference. I work with some serious gurus (internationally known experts on the Cisco 10000/12000 platforms etc) who DONT even have a CCNA...
In the end regarding the Comp. Sci vs. Comp. Eng. debate, my opinion is that you cannot compare them. Comp Sci is much "easier" (true, it's different, but it *is* easier). 90% of the Comp Eng dropouts I know went to Comp. Sci... If I wan a decent programmer, I will hire a Comp. Scientist whereas for everything else, Comp. Eng all the way. And regarding the Tuks Comp. Eng programme, it is very good and in all fairness very diverse (referring to the jack of all trades statement). what this means is you can do a variety of things (including work in a call center LOL). I for example, do not touch circuits OR wrote any code (and glad! on both counts...). The number of doors that this degree opens is very useful whereas I feel with CS you are more specialised and "boxed in" - not necessarily a bad thing though! I will admit that in CS, your programming is more focused whereas in CE the aim is to expose you to a lot of languages and then to develop your programming skills in a DSP/Hardware environment. That in my mind is the key difference. So you can't really compare Oranges and Naartjies
Best bet, stick to CS for hardcore programming. Otherwise go with Comp. Eng. and in BOTH cases start certifying on a Cisco (or even Juniper) path from final year!
Btw, Comp Eng is NOT only about circuits etc. I'd rather say you get a decent exposure to the electronic engineering influence - call it a heavy bias. I mean we even did subjects on economics, environmental management, engineering drawing, professional practice, innovation etc in amongst all that hardcore maths and signal processing.
I'd like to close with saying that I don't regret doing Comp Eng for a second (maybe the Masters, no wait definitely the Masters LOL) as I have managed to get myself a very nice job that I enjoy (and have had a good few opportunities to make some fairly big changes that are noticeable, not gonna say more). I believe the above is the case for about at least 50% of my mates etc who did the degree. So moral of the story, make sure you are in the right degree and try to make the best of it!
