It's painfully obvious you're new to this conversation. Yes, the prices of computer hardware is outrageous right now. But the big factor that you forgot to consider with your 'cheap' pc is that the major manufacturers, like the Dell you so prominently advertised, create proprietary systems that are designed to be thrown in the trash. Oh, like the HP junk laptop that came with a hard drive too small to run Windows update (hint, wipe and install Ubuntu).
But, if you're still convinced that tossing your money and computer away while promoting even more e-waste is a good idea, may I recommend the tech savvy giant, WalMart. I hear their Gateway... I mean Shenzhen Bmorn computers are just amazing (note the sarcasm).
