Agree, I would much rather rent my apartment if I could, but the way the market looks here it's not an option.
Renting is just like insurance, you pay a premium so that others take the greater financial risk: You're not tied down, you can move anytime, and you don't have to care about the housing market or interest rates. For some people this is worth it, for some it's not. Your mileage may wary.
The only other problem I have with his text is that he seems to suffer from analysis paralysis by not buying a computer for years since they drop off in value so fast. There's also a value in having a computer, or whatever other item, in that time.
Yes, if you wait one year you'll get a faster computer than what you can buy now, but you'll also be stuck with your current computer for one more year. How much does that cost? Sometimes you just have to suck it up.
