Too bad about Borders. I always liked going there, and regularly bought from them. I must say, however, that the new e-books combined with Amazon and similar online companies make book buying a better experience unless I'm just browsing. Even browsing is easier online today because you can sample excerpts of many books, or at least find reviews, before buying.
My take on Borders is that there's only so much demand for big box book stores, and the industry over-built when times were good. Now the industry is in one of its periodic down cycles and there's a shakeout happening.
Long live Barnes and Noble!
