This is great news (although no doubt it will be quite a while before they start delivering to those like me who live in the middle of nowhere!). The biggest problem with online retailers has been the shipping, especially with regards to PC parts. For example, a couple of months ago a PSU died. Now you would think that a power supply would be a pretty common part, but yet all the major PC retailers anywhere close to me (again, living out in the middle of nowhere, but within an hour drive I could get to a Best Buy, Office Depot, Office Max, Wal-Mart, Target, etc.) didn't have a PSU and because of that I had to order it online and wait a couple of days to use that computer again.
The same thing is true when I'm working on a project and realize that I ran out of some component (or I broke it!). It used to be that Radio Shack was really good at keeping just about any part I needed in stock, but anymore their electronics hobby section is much, much, smaller than their Cell Phones/PC section.
