Getting way off-topic. I apologize...
But when it comes to the internet, why should you need to visit a web-based mega office supply store, for example, if you are looking for pencils?
Because people still prefer the one-stop shop, even online. Sure, the Internet does away with the need to drive, but it also does away with the simplification of an in-store purchase (swipe-and-sign).
Repeatedly filling out all of the information that most online stores require at the point of purchase, or signing up and maintaining accounts on multiple websites, is probably a big enough disincentive for most people.
There's also the issue of how fine you want the separation. I buy all of my personal computer equipment from a single online store. You can argue that since it's all computer related, there's no issue, but I could easily point out that many of the components that make up a computer are actually quite unrelated to each other. Why, then, should I go to this online store for a sound card rather than visit a website dedicated to sound cards only?
