Borders Files for Bankruptcy

It's official - Borders has filed for Chapter 11 bankruptcy.  The news is all over the net.  Does this mean the beginning of the end of mega-bookstores?  Barnes&Noble is rumored to be in trouble too.  Will this help the Mom&Pop small bookstores?  Or are they all destined to go away in favor of Amazon and other online sites?  Personally, there's something about spending an hour or so browsing in a bookstore that you just can't get from Amazon.  Anyway, here's one of many articles on Border's problems, this one from The NYTimes.
