Been thinking on cell phones and libraries for a while now, and I finally put together an article on the topic for Library Journal -- "Phones are Everyware" is in the 15 July issue.
Leave some feedback about it if you like. I've been pleased to see lots of librarians moving away from supporting the ban (Michael Stephens has a great post about it at Tame The Web). So many of us are still trying to crack down, trying to keep the new technology out -- maybe librarians of the old guard smell the doom of 20th Century models of librarianship. It doesn't have to hurt, though. And it's true that too many lessons of the 'old guard' are lost on 'young guard' librarians.
Libraries are only doomed if they fail to subvert the ubicomp and fail to put it in service for their own future. This thing is coming hard and fast.
