Wow...
Just installed an update to Win7 that makes it compatible with SD cards over 32 GB.
I had to sit and ponder for a minute to think of something the size of a postage stamp that holds 32 GB. They run around $90, and you can actually buy a 64 GB SD card on Amazon for about $245.
Remember Fahrenheit 451, where books were preserved by memorizing them? A 64GB chip can carry something like 32 million pages of text, and you can hide it under your tongue. Digital readers are taking off big time, and I expect they will become quite common and cheap in future years.
Take that, bookburners.
