As much as I love eBooks (Kindle, iPad, iPhone, laptop), I have to wonder how these will hold up to the test of time. We visited a wonderful library in Switzerland and viewed books written in the 800's.
Having worked in IT for many years, I have seen data lost forever because technologies changed or destroyed the media rendering this information useless or unreadable - paper tape, magnetic tape in all formats, floppy discs... Just thinking.
