You're missing the point though...you have a full-time job and probably get paid a fairly good amount. Not to mention your wife probably also works and earns a salary. A student on the other hand either has no time to work, or has to work to try to pay off his or her loans/school bills. I know for me when I was in college, I didn't have time to get a job because I had practice in the AM before classes, and practice in the PM after classes, then I would eat dinner and then go back to my dorm and do homework...so I didn't really have time to get job, sorry.
So for you to compare yourself to a student isn't really relevant.
No, the point is you don't have to be a student to be short on cash.... people out in the 'real world' also have cash flow issues, just becuase I have a job doesn't mean I can instantly afford anything. I get paid ok but nothing wonderful, my wife does not work and i have two children. We mostly live from paycheck to paycheck, and so $129 for the new OS is a big deal to me it is more than I can afford all at once and so I will need to save up to get it. My point is, I am perfectly ok with paying $129 even though I can't afford it, I think it's a wonderful price and I don't think I or any one else deserves a discount from Apple just becuase of their personal financial situation wether they are a student or otherwise.
