I put money towards mine, but my parents basically bought it for me.
I don't really have a job and my parents would rather have me work hard in school and do sports and things I like instead of spending all my time working. They believe that I am a kid and I shouldn't spend all my time working, whether it be school, homework, or doing a job.
Last summer I worked for about 2 weeks doing a small job doing technology work. This upcoming summer I plan to work more of the summer (depending on the school's budget) doing computer work and possibly working/volunteering at a pharmacy (career aspiration).
All the money I do make I put into the bank, which basically is a savings account because I never have taken money out of it. Some of it gets invested.
My computer is 3 years old and up until recently I haven't really found the need for a new computer but thats only because its becoming quirky. It does what I have to do, it's not the latest and greatest but it gets the job done- basic stuff + advanced stuff photoshop + video editing, etc.
I think its best to save money. Clearing out your savings to buy something is stupid, especially a computer which becomes worthless in a matter of years I don't think is a wise decision.
I'll be honest, I don't pay for much of my stuff. My parents pay for pretty much everything I I do/own and I am thankful. Even if I worked everyday after school and every weekend there is no way I could afford to buy a car, gas, and insurance, let alone a computer.
Basically my saved money will be the money that I use once I get out of college.
