I have never been hoarder of *books*. I only buy ones that are very, very special. Like books by JRR Tolkien or Terry Pratchett, or ... . From my early reading years I understood that I would never be able to buy and *store* all the books to satisfy my appetite. I was content with borrowing books from 5 or more libraries (at the same time!). During my high school years I was able to bring in and read through a foot high pile of library books every week.
I do hoard e-books. Not that I spend hours and hours hunting books, but when there is opportunity to download something free, I do not hesitate.
I also hoard computers, notebooks, e-book readers, general hardware, power tools, hand tools, carving chisels, grinders, wood for carving (it takes years and years for a block of wood to dry properly ;- ) )
At the moment I have about 9 working computers at home, and several more at work that my wife does know about ... yet. Including absolutely wonderful microwax 3300 in working condition. Now I just need that DIGITAL VT400 terminal our technicians promised me
