I will have a compsci degree in 8 weeks time. I've found it very enjoyable.
A lot of stuff we learn isn't really ever going to be useful to me (all the stuff we learn IS useful and used in the real world, but obviously unless you want to write a compiler courses on compiler theory wont be particularly useful to you in the future for example), but its qutie theoretically interesting and challenging.
Its also very diverse. You will probably have a lot of choice on what you do. For my dissertation I developed a system to predict the outcome of greyhound races and place bets on them, so it can be quite fun!
Who is compsci for:
==============
I would say anyone who involves solving logic puzzles, enjoys working out how things work, possibly with an interest in engineering.
Compsci will NOT teach you how to program (unless you go to one of the 'worse' universities). They might teach you a little, but as said in the link it will be 15% or less if you go to a good university.
Job prospects:
==============
Well I've been offered a 30k job (will probably do a Phd instead though), which is good but probably well above average for a compsci graduate. Job prospects are good as long as you go to a good uni.
