A computer engineering degree is very useful, seeing as, in spite of the high-tech market meltdown, computers will continue to grow to a more prominent role in society.
There are plenty of jobs for computer engineering graduates, and salaries have a wide range. I know of people personally who made around $50000 US upon graduating (and the people, while intelligent, weren't superstar students or anything), although admittably, that was when the market was a lot hotter. It also depends on where you want to work... if you work in Silicon Valley, you'll probably make more money than in some rural town, but if you work in Silicon Valley, be prepared to pay a LOT for housing... it certainly isn't cheap.
