At the end of the day, you still have to:

1) Make/sell a good product or service at a reasonable price

Or

2) Be really, really good at convincing/tricking people into paying for your product/service

If you do both 1 and 2 well, you're going to do well. Just one, and you'll be okay. If you're just mediocre at both, then good luck. Competition is fierce in the basic product/service sectors on the Internet now that the barrier of entry for anyone setting up an Internet business is so low.
