Just a note: Amazon's file transfer over wireless seems on the fritz today-- it rejected a perfectly good .DOC and .TXT file (just trying them out) and the tech support number was busy. Probably getting lots of transfers and having problems would be my guess. In the meantime, a formatted PDF file translated and was sent to my Kindle perfectly fine on Friday.
USB transfers of TXT and HTML work fine as well.
They should release a standalone file converter....yeah, I know, there are financial reasons for not doing so, and the converter would be ripe for reverse engineering.
Meantime, if my Sony had search and note functions, I'd much prefer it.
