Thoughtful comments from Siva Vaidhyanathan on the Kindle:

As far as the dream of textual connectivity and annotations — making books more “Webby” — we don’t need new devices to do that. Nor do we need different social processes. But we do need better copyright laws to facilitate such remixes and critical engagement.
So consider this $400 device from Amazon. Once you drop that cash, you still can’t get books for the $9 cost of writing, editing, and formating. You still pay close to the $30 physical cost that includes all the transportation, warehousing, taxes, returns, and shoplifting built into the price. You can only use Amazon to get texts, thus locking you into a service that might not be best or cheapest. You can only use Sprint to download texts or get Web information. You can’t transfer all you linking and annotating to another machine or network your work. If the DRM fails, you are out of luck. If the device fails, you might not be able to put your library on a new device.
All the highfallutin’ talk about a new way of reading leading to a new way of writing ignores some basic hard problems: the companies involved in this effort do not share goals. And they do not respect readers or writers.
I say we route around them and use these here devices — personal computers — to forge better reading and writing processes.
