The homepage of Amazon today presents a "personal letter" about Kindle Fire from Jeff Bezos. That is a nice touch. It is not frequent when business owners talk to you. Even though the letter has probably composed by multiple teams it still gives a good impression that Jeff Bezos cares about his customers and considers it important to talk "directly" to them. Inclusion of social share option at the bottom of the letter is also a good idea to spread the word.
Am I going to buy Kindle Fire? No, I am still pretty happy with my iPad :). $49.99 one-year 4G data package sounds attractive if I didn't have a table yet. Also Kindle Fire HD 4G is not yet approved by FCC.
