I posted this question earlier today on SuperUser: What was your biggest waste of money and what should you have bought instead?
I think it's a legitimate question, because I've spent a lot of money on computer junk, electronics, and software that I now realize would have been better spent on other things. Spending too much money on technology has prevented me from picking up other hobbies. Also, trying to get the best bargain has prevented me from getting different technology that might have suited my needs a little better. I was curious whether others had come to a similar realization, and what kinds of things they felt they had wasted money on.
Unfortunately for me, my question has been closed with the explanation, "Not a real question," and I was told to go read the FAQ. Of course, I've already done that, and I don't see the difference between my question and the tons of questions like these (which I also think are valid questions):
https://superuser.com/questions/1599/what-is-the-worst-depiction-of-computer-use-in-a-movie
https://superuser.com/questions/32799/what-is-your-oldest-hardware-that-still-works
I've been told that someone who voted to close the question didn't see any value to future visitors of the site. I would like to think that the future value is that others can learn from our mistakes and think twice before buying something they don't need, when they could save up for something else instead.
