I do most of my reading on a PC and rarely use my PRS 505 to read when waiting for my wife in offices, etc.

Thus, my book buying strategy will be to buy from the lowest cost source from the following four to read on my PC with only one book maintained on my Sony PRS 505. I don't really need the Amazon Kindle, BN Nook or the more advanced Sony eReaders.

My four sources to be used after title selection:

1. Kindle for PC.
2. Sony ebook Library.
3. Microsoft Reader.
4. BN eReader.

Both my wife and myself read all our books on my PC. That four way competition should keep book buying costs at a minimum.
