Amazon’s Kindle is back in stock and has been for a week or so. A nice personal-type of unboxing is available here (complete with wife and baby) at Josh Bancroft’s Tiny Screenfuls.
I have a hard time laying out $400 for a grey-scale device but I think that’s just a rationalization on my part. For $400 you get portable reading of LOTS of titles that are stored in the device or (pretty much) immediately downloadable from Amazon. Books and publications are relatively cheap so, all in all, if you’re a reader, it’s probably worth it.
