Great toy and sanity saver
Maybe try buying from the states?
I bought my 505 for ~$230 USD, and use it regularly.
The 505 seems to run longer on a charge, as well as responding to page turns faster than the PRS-500 I initially had, and ended up sending to my mother, who got me addicted to books in the first place.
Admittedly, they could have possibly done with a couple less buttons, but the buttons that are there are usefull, other than the afore mentioned music control buttons.
As was also mentioned, the music function kills battery life, so I just don't load any music. If I want to listen to music, I turn on a radio, or carry an iPod.
I've easily read RTF files regularly, as well as the LRF files, since the publisher that I have purchased from now supplies them as well as the other 5-6 formats that they had. (www.baen.com, and www.baen.com/library/)
All in all, the icon says it for me. If you're an avid reader, and can live without the complete tactile sensation of paper under your fingers, this makes an excellent addition and a way to cary far more books in your pocket than would normally be possible!
