As far as doing QA, where I work (and other places I have worked) I usually see people move from QA into development when they have paid their dues. If it means getting your foot in the door to a good company, or doing what you want (working with Perl, Linux, etc...) then go for it!

I wouldn't be too picky right out of college... but I wouldn't grab anything that comes along. I don't think you would get held into being a QA field for life (same with doing SA).

The biggest experience you will get is working in this 'biz'. Dealing with clients, PHBs, idiots, egos, and good people you will learn from will likely be more of what you concentrate on at first.

No matter what.. good luck to you!

Cheers,
