I will give Jeff credit for one thing. He did bring out e-ink into the mainstream. I'm a gadget freak and I'd heard of E-ink before, but not until I heard about the Kindle was I interested in e-ink readers.
Now with that said, I bought the Sony 505 instead.

The Kindle I feel is good for someone who is not very technically inclined, and doesn't have a pre-existing ebook library. They did integrate well with Amazon, making it easy to spend money, which is good for Jeff, not the people
Personally, I already had a substantial collection of LIT files, and an iphone. So wireless connectivity was moot.
If Jeff had designed the Kindle better, I would have bought one in a heartbeat. The look of it throws me off of it everytime. Too plastic and odd.
