Dream Job - Writing Reviews?

People complain about reviews that they see in established computer sites and such.

I've often wondered what it's really like to be a reviewer. Do they still have that feeling of 'oh cool, another gadget to review, heaven!' or do they get jaded and think 'what the hell, another piece of junk that just looks like the other one, but they're a big sponsor, I suppose.'

Do they get stressed? Do they get any freedom on how they write reviews? Are they forced to do write things in a certain way due to advertising pressure, or SEO?

Do these companies want reviewers to a have surplus amount of passion and let them get away with drivel once in a while because reviewers that can write quality stuff get burnt out quicker?
