Tuesday for me (Amazon Prime ftw!
Will have it side by side with the Sony Reader to compare.
Oh, and Amazon have already assigned it a name and I've assigned it an email address and bought my first book! So far the whole Kindle infrastructure is living up to the expectations for such a device coming from Amazon.
Kinda hoping the display contrast might be a bit better than on the Sony, but it sounds like they use pretty much the same display.
