Why on earth would you want to pay a bank money so that they can say you're OK to lend money to, so that you can pay another bank money in interest. Just pay cash. Just because it's 2009 doesn't mean we can't live with the common sense they had in 1909.
Debt is the main reason the economy is the way it is right now. People and businesses buying more than they can afford and being leveraged up to their eyeballs. They lose one customer, or miss a day of work, and all hell breaks loose.
Because the guy is trying to build credit. Even if he doesn't need credit now, doesn't mean that in the future he won't need a home loan, a car loan, or anything. He might need $5000 braces for his kid and may need to finance it. Depending on the type of job you apply for, they might run a credit report to see if he is trustworthy. As the economy gets worse, banks are going to be more wary of loaning any money. A spotless credit record, or at least one far more positive than negative, is going to be essential.
I'm not advocating going into debt for a laptop, my post was that - if cwwilson is set on buying a $2000 computer, he can use the opportunity to get a paid off loan on his credit report, which will look much better than the situation he is in now.
Using my scenario above, a $2000 loan for 12 months @7.5% will cost him $82 in interest. $2500 in a savings account for 12 months at 2.5% interest will earn him $63 in interest. So for 19 dollars (less than 2 dollars a month) the guy builds a positive credit score. In his situation it would probably be the best $19 he will ever spend.
There were banks in 1909 too. My Grandparents bought their first house in the 30's on a bank loan. The main difference is that back then it was my Grandfather's standing in the community and his job as a steelworker that convinced the bank to lend him the money. Nowadays, loans are granted based on a arbitrary number (credit score) spit out by a computer somewhere that the average consumer has very little control of.
So davidg4781, if you have the means to pay for a $150,000 house in cash (which in my area gets you a 30 year old fixer upper with broken appliances and leaking roof), then I'm happy for you. But paying cash for a house is not going to happen for the majority of the working class - and that is why you need credit.
