Thanks, Folks.
DX arrived and it's amazing! Just finished a book today. The DX makes for a beter readin experience, IMHO.
I like my Kindle Keyboards, but this addtonal screen real estate is the way to go.
Before I left for the non 3G area, I made sure to download books, etc. using 3G. Al is well. Using Clibre one book did not transfer and open. "War Horse" that I purchased form amazon. I have it in Calibre and moved it to my Kindle and it won't open. I'll try another book just to see what happens.
