If you have a subscription to WSJ.com, you can use Calibre to read WSJ on your Kindle. Check it out at http://calibre.kovidgoyal.net/. You can also read many newspapers and magazines this way, for free. Wonderful program.
Calibre will convert almost any format out there to almost any other format quite easily. Accurately is another matter. Some PDFs convert well (book formats usually), but newspapers or books with columns or inset text boxes (think of the for Dummies series) can be almost unintelligible by the time its done converting.
Calibre has "recipes" for the download quite a number of periodicals. I have a daily task which download the "free" version of the WSJ and automatically emails it to email@example.com. I have the K3 with only wifi so the download costs nothing.
It took a bit of messing around to get it working but now I get three periodicals delivered every day to my kindle.
WSJ now offers a Tablet Edition, an Online Edition, and a Kindle Edition. There is no information out there comparing these side-by-side. Is the Kindle Ed the same as the Tablet Ed? I understand Kindle Ed isn't the same as Online Ed, but does the Tablet Ed give access to the Online archives (a major deficiency in the Kindle Ed, in my opinion)?
