I personally make quite a good living. I have a lot of money in the bank. Why do I have a lot of money? Because I don't waste it on products that are overpriced and offer no bang for the buck. Also, many people who are trashing the MBA have a MBP....which of course, costs more. Being a smart consumer means spending wisely. If the MBA is a wise buy for you, great. Just keep in mind that it isn't for everyone. And also keep in mind that most poor people aren't on the cutting edge of electronics, and probably don't browse macrumors.
I didn't mean 'poor' in the literal sense.
IMO, the opposite of poor in the context I used it in is carelessly spending money the way I'm going to do when I buy my MBA. Do I care that I'm spending 2K on a laptop that doesn't meet the standards set my the MBP? No... because I see past the price which is what I want a lot of people to do. Criticize the MBA all you want, but don't criticize it in relation to price.
