I know it's hip with the kids to be cynical these days, but surely you jest...

The legal term is "contract."
> This price can be higher or lower, you cannot know beforehand.
Yep. That's kind of the point. Risk versus reward and all that.
> It's not a replacement for a salary or a stake in the company.
Not directly, no. Neither is health insurance, 401k, company provided meals or other benefits, but all of these things are perceived by most to have at least some marginal value.

C'est la vie

Or, ya know, you end up with a company that has good growth potential and those options work out in your favor, which is actually typically the case btw. On average, the market has improved over time. I'm guessing you were burned either b/c the company was high risk (which means you had the potential to do VERY well conversely) or you were hit by the downturn which also affected almost all stock, so not really related to options in that case.
> I have this impression that some misrepresent options with stock
Then some are idiots for agreeing to something they don't understand.
