Books. It's hard to get along without them.
I love to read, to become lost in some other world, and then to come out of it and think about it. In the past 5 days we have acquired a new bookshelf to help organize our piles and piles of books...
The accessibility of reading material in the palm of your hand is pretty cool. But still, it can't really compare, can it. It's like when LPs were replaced by cassettes and then CDs, and then MP3s; we lost the cover art and all of those liner notes; the feel and look of things changed. It's like wine in a box: it gets the job done, but there is no panache.
I already miss the books themselves. Going completely electronic seems unlikely.
