Kindle Experiences
I feel that the device is well thought out and the user experience is very good. The main issue I have is that I constantly keep pressing the buttons on the two sides of the device. I feel that the buttons should be a bit smaller.

Transferring documents to Kindle
Emailed a Microsoft Word document and a jpeg file to the Kindle. They both showed up in about 5 minutes. The tables in the word documents were converted to text. Overall, I am quite satisfied with the function. It did accept a pdf even though the documentation does not list that as a supported format.
I am not very happy with the $0.10 I have to pay for receiving each of the documents.
