I am still sad that Border's is closing... it was my favorite "big box" style bookstore. But my second choice for mega-bookstores has always been the B&N store at the Arbo. Even though they don't offer the same variety of games, music, and movies that Border's offered, they do have a nice selection of books, magazines, and gifts.
This location is popular with the local teachers as well... when my daughter was at Providence High School, her AP English teachers would submit their required reading lists to this B&N location so that they could stock up on the books that the students would be needing. Very convenient! (You could often find the books cheaper online, but we were procrastinators, so it was much quicker & easier to just stop by B&N!)
This location has a Starbucks in the center of the bookstore that really gets packed at times. It is a popular place for friends to meet for a cup of coffee and a chat.
